Rotary Clamp Cylinder: Standard Series MKPrecautionsBe sure to read this before handling.Refer to back page 1 for Safety Instructionsand “Precautions for Handling PneumaticDevices” (M-03-E3A) for Common Precautions.Precautions for Designing and Mounting ArmsWhen arms are to be made separately, their length and weight should be within the followingrange.1. Allowable bending momentUse the arm length and operating pressure in Graph (1) to select an allowable bendingmoment loaded piston rod.CautionClamp Arm Mounting1. Use a clamp arm that is available as an option.To fabricate a clamp arm, make sure that theallowable bending moment and the inertialmoment are within the specified range.If a clamp arm that exceeds the specified valueis installed, the internal mechanism in thecylinder could become damaged.Ensuring Safety1. If one side of the piston is pressurised bysupplying air with the clamp arm attached, thepiston will move vertically while the clamp armrotates. This operation could be hazardous topersonnel, as their hands or feet could getcaught by the clamp arm, or could lead toequipment damage. Therefore, it is importantto secure as a danger zone a cylindrical areawith the length of the clamp arm as its radius,and the stroke plus 20 mm as its height.Installation and Adjustment/Clamp Arm Removal and Reinstallation1. During the removal or reinstallation of theclamp arm, make sure to use a wrench or avise to secure the clamp arm before removingor tightening the bolt.This is to prevent the bolt tightening torquefrom being applied to the piston rod, whichcould damage the cylinder’s internal mecha-Mounting Bolt for MKBMounting: Mounting bolt for through-hole type isavailable.Ordering: Add the word “MKB” to the mountingbolt size.Example) M5 x 75 L (MKB)Mounting boltGraph (1)MK50/63Arm length l (cm)Moment of inertia (kg·m 2 )MK32/40MK20/25MK16Operatingrange2.

Rotary Clamp Cylinder: Heavy Duty Type Series MK2PrecautionsBe sure to read this before handling.Refer to back page 1 for Safety Instructionsand “Precautions for Handling PneumaticDevices” (M-03-E3A) for Common Precautions.CautionClamp Arm Mounting1. Use a clamp arm that is available as an option.To fabricate a clamp arm, make sure that theallowable bending moment and the inertialmoment are within the specified range.If a clamp arm that exceeds the specified valueis installed, the internal mechanism in thecylinder could become damaged.Ensuring Safety1. If one side of the piston is pressurised bysupplying air with the clamp arm attached, thepiston will move vertically while the clamp armrotates. This operation could be hazardous topersonnel, as their hands or feet could getcaught by the clamp arm, or could lead toequipment damage. Therefore, it is importantto secure as a danger zone a cylindrical areawith the length of the clamp arm as its radius,and the stroke plus 20 mm as its height.Installation and Adjustment/Clamp Arm Removal and Reinstallation1. During the removal or reinstallation of theclamp arm, make sure to use a wrench or avise to secure the clamp arm before removingor tightening the bolt.This is to prevent the bolt tightening torquefrom being applied to the piston rod, whichcould damage the cylinder’s internal mecha-Mounting Bolt for MK2BMounting: Mounting bolt for through-hole type isavailable.Ordering: Add the word “MK2B” to the mountingbolt size.Example) M5 x 75 L (MK2B)FlatwasherMounting boltArm length l (cm)20108642Precautions for Designing and Mounting ArmsWhen arms are to be made separately, their length and weight should be within the followingrange.1.

Rotary Clamp Cylinder: Double Guide Type Series MK2TPrecautionsBe sure to read this before handling.Refer to back page 1 for Safety Instructionsand “Precautions for Handling PneumaticDevices” (M-03-E3A) for Common Precautions.CautionClamp Arm Mounting1. Use a clamp arm that is available as an option.To fabricate a clamp arm, make sure that theallowable bending moment and the inertialmoment are within the specified range.If a clamp arm that exceeds the specified valueis installed, the internal mechanism in thecylinder could become damaged.Ensuring Safety1. If one side of the piston is pressurised bysupplying air with the clamp arm attached, thepiston will move vertically while the clamp armrotates. This operation could be hazardous topersonnel, as their hands or feet could getcaught by the clamp arm, or could lead toequipment damage. Therefore, it is importantto secure as a danger zone a cylindrical areawith the length of the clamp arm as its radius,and the stroke plus 20 mm as its height.Installation and Adjustment/Clamp Arm Removal and Reinstallation1. During the removal or reinstallation of theclamp arm, make sure to use a wrench or avise to secure the clamp arm before removingor tightening the bolt.This is to prevent the bolt tightening torquefrom being applied to the piston rod, whichcould damage the cylinder’s internal mecha-Mounting Bolt for MK2TBMounting: Mounting bolt for through-hole type isavailable.Ordering: Add the word “MK2TB” to themounting bolt size.Example) M5 x 115 L (MK2TB) 4 pcs.Mounting boltFlatwasherNote) Be sure to use a flat washer to mountcylinders via through-holes.Graph (1)MK2T50/6320MK2T32/40Arm length l (cm)108642Precautions for Designing and Mounting ArmsWhen arms are to be made separately, their length and weight should be within the followingrange.1.

Series MK/MK2/MK2TAuto SwitchesPrecautions 1Be sure to read this before handling.Warning1. Confirm the specifications.Read the specifications carefully and use this product appropriately.The product may be damaged or malfunction if it is used outsidethe range of specifications of current load, voltage, temperatureor impact. We do not guarantee any damage in any casethe product is used outside of the specification range.2. Keep wiring as short as possible.As the length of the wiring to a load gets longer, the rush currentat switching ON becomes greater, and this may shortenthe product’s life. (The switch will stay ON all the time.)Use a contact protection box when the wire length is 5 m or longer.Although wire length should not affect switch function, use a wire100 m or shorter.If the wiring is longer it will likely increase noise although thelength is less than 100 m.When the wire length is long, we recommend attaching the ferritecore to the both ends of the cable to prevent excess noise.Since the solid state switch is a semiconductor switch whichhas no contacts, no contact protection box is needed.3. Do not use a load that generates surge voltage. If asurge voltage is generated, the discharge occurs atthe contact, possibly resulting in the shortening ofproduct life.If driving a load such as a relay that generates a surge voltage,use a switch with a built-in contact protection circuit or use acontact protection box.Although a zener diode for surge protection is connected at theoutput side of a solid state switch, damage may still occur if thesurge is applied repeatedly. When a load, such as a relay orsolenoid, which generates surge is directly driven, use a type ofswitch with a built-in surge absorbing element.4. Caution when using in an interlock circuitWhen an auto switch is used for an interlock signal requiringhigh reliability, devise a double interlock system to avoid troubleby providing a mechanical protection function, or by also usinganother switch (sensor) together with the auto switch. Also performperiodic maintenance and confirm proper operation.5. Do not make any modifications (including exchangingthe printed circuit boards) to the product.It may cause human injuries and accidents.Design and SelectionCaution1. Use caution when multiple actuators are used andclose to each other.When two or more auto switch actuators are lined up in closeproximity to each other, magnetic field interference may causethe switches to malfunction. Maintain a minimum cylinder separationof 40 mm. (When the allowable interval is specified foreach cylinder series, use the indicated value.)Use of a magnetic screen plate (MU-S025) or magnetic screentape can reduce the interference of magnetic force.2. Take note of the internal voltage drop of the autoswitch.1) Auto switches with an indicator light (except Model D-A96,A96V, A76H)• If auto switches are connected in series as shown below,take note that there will be a large voltage drop because ofinternal resistance in the light emitting diodes. (Refer to theinternal voltage drop in the auto switch specifications.)[The voltage drop will be “n” times larger when “n” autoswitches are connected.]Even though an auto switch operates normally, the loadmay not operate.Load• In the same way, when operating under a specified voltage,although an auto switch may operate normally, theload may not operate. Therefore, the formula below shouldbe satisfied after confirming the minimum operating voltageof the load.Supplyvoltage – Internal voltagedrop of switch> Minimum operatingvoltage of load2) If the internal resistance of a light emitting diode causes aproblem, select a switch without an indicator light (Model D-A90, A90V, A80(H)(C)).3) Generally, the internal voltage drop will be greater with a 2-wire solid state switch than with a reed switch. Take the sameprecautions as in 1).Also, note that a 12 VDC relay is not applicable.3. Pay attention to leakage current.With a 2-wire solid state switch, current (leakage current) flowsto the load to operate the internal circuit even when in the OFFstate.Operating current of> Leakage currentload (OFF condition)If the criteria given in the above formula are not met, it will notreset correctly (stays ON). Use a 3-wire switch if this specificationwill not be satisfied.Moreover, leakage current flow to the load will be “n” times largerwhen “n” auto switches are connected in parallel.4. Ensure sufficient clearance for maintenance activities.When designing an application, be sure to allow sufficient clearancefor maintenance and inspections.Back page 2

Series MK/MK2/MK2TAuto SwitchesPrecautions 2Be sure to read this before handling.Mounting and AdjustmentWarning1. Operating manualInstall the products and operate them only after reading theoperating manual carefully and understanding its contents. Also,keep the manual where it can be referred to as necessary.2. Do not drop or bump.Do not drop, bump or apply excessive impacts (300 m⁄s 2 or morefor reed switches and 1000 m⁄s 2 or more for solid state switches)while handling. Although the body of the auto switch maynot be damaged, the inside of the auto switch could be damagedand cause a malfunction.3. Mount auto switches using the proper fastening torque.When a switch is tightened beyond the range of fastening torque,the mounting screws, auto switches, auto switch mountingbracket, etc. may be damaged. On the other hand, tighteningbelow the range of fastening torque may allow the switch to slipout of position. (Refer to the auto switch mounting for each seriesregarding auto switch mounting, moving, and fastening torque,etc.)4. Mount an auto switch at the center of the operatingrange.Adjust the mounting position of an auto switch so that the pistonstops at the center of the operating range (the range inwhich a switch is ON). (The mounting position shown in a catalogindicates the optimum position at stroke end.) If mounted atthe end of the operating range (around the borderline of ONand OFF), operation will be unstable or the service life will beshortened.When the auto switch is used to replace old series autoswitch, it may not activate depending on operating conditionbecause of its shorter operating range.Such as• Application where the stop position of actuator mayvary and exceed the operating range of the auto switch,for example, pushing, pressing, clamping operation, etc.• Application where the auto switch is used for detectingan intermediate stop position of the actuator. (In thiscase the detecting time will be reduced. )In these applications, set the auto switch to the center of therequired detecting range.Caution1. Do not carry an actuator by the auto switch lead wires.Never carry a cylinder (actuator) by its lead wires. This may notonly cause broken lead wires, but it may cause internal elementsof the auto switch to be damaged by the stress.2. Fix the auto switch with appropriate screw installedon the auto switch body. If using other screws, autoswitch may be damaged.WiringWarning1. Confirm proper insulation of wiring.Be certain that there is no faulty wiring insulation (contact withother circuits, ground fault, improper insulation between terminals,etc.). Damage may occur due to excess current flow into aswitch.2. Do not wire with power lines or high-voltage lines.Wire separately from power lines or high-voltage lines, avoidingparallel wiring or wiring in the same conduit with these lines.Control circuits, including auto switches, may malfunction dueto noise from these other lines.Caution1. Avoid repeatedly bending or stretching lead wires.Repeated bending or tensile force applied to the lead wire maycause the sheath to fall off or disconnection of the wire.If bending or tensile force are not avoidable, fix the lead wireclose to the switch and allow a bend radius of R40 to 80 mm orlarger. Consult SMC for details. Stress and tensile force appliedto the connection between the cable and switch increases thepossibility of disconnection.Fix the cable in the middle so that it is not movable in the areawhere it connects with the switch.2. Be sure to connect the load before power is applied.If the power is turned ON when an auto switch is not connectedto a load, the switch will be instantly damaged because of excesscurrent.It is the same as when the 2-wire brown cord (+, output) is directlyconnected to the (+) power supply terminal.3. Do not allow short circuit of loads.If the power is turned ON with a load in a short circuited condition,the switch will be instantly damaged because of excesscurrent flow into the switch.Model D-M9(V) and all models of PNP output type switchesdo not have built-in short circuit prevention circuits. If loads areshort circuited, the switches will be instantly damaged, as in thecase of reed switches.Take special care to avoid reverse wiring with the power supplyline (brown) and the output line (black) on 3-wire type switches.Back page 3

Series MK/MK2/MK2TAuto SwitchesPrecautions 3Be sure to read this before handling.WiringCaution4. Avoid incorrect wiring.A 24 VDC switch with indicator light has polarity. The brownlead wire is (+) and the blue lead wire (–).1) If connections are reversed, a switch will operate, however,the light emitting diode will not light up. (For D-A79W, theoutput signal will be sent, but the LED will not operate.)Also note that a current greater than that specified will damagea light emitting diode and it will no longer operate.Applicable models:D-A93, A73(H)(C), A79W1) If connections are reversed on a 2-wire type switch, the autoswitch will not be damaged if protected by a protection circuit,but the switch will always stay in an ON state.However, it is still necessary to avoid reversed connections,since the auto switch could be damaged by a load short circuitin this condition.2) If connections are reversed (power supply line + and powersupply line –) on a 3-wire type switch, the switch will be protectedby a protection circuit. However, if the power supply line(+) is connected to the blue wire and the power supply line(–) is connected to the black wire, the auto switch will bedamaged.The D-M9 does not have built-in short circuit protectioncircuit. Be aware that if the power supply connection isreversed (e.g. (+) power supply wire and (–) power supplywire connection is reversed), the auto switch will be damaged.5. When the cable sheath is stripped, confirm the strippingdirection. The insulator may be split or damageddepending on the direction. (D-M9, M9W,M9A(V)L only)Recommended ToolModel nameWire stripperModel no.D-M9N-SWY∗ Stripper for a round cable (ø2.0) can be used for a 2-wire type cable.Operating EnvironmentWarning1. Never use in an atmosphere of explosive gases.The construction of auto switches is not intended to prevent explosion.Never use in an atmosphere with an explosive gas sincethis may cause a serious explosion.2. Do not use in an area where a magnetic field is generated.Auto switches will malfunction or magnets inside actuators willbecome demagnetised.3. Do not use in an environment where the auto switchwill be continually exposed to water.Although switches, satisfy IEC standard IP67 construction (JISC 0920: waterproof construction), do not use switches in applicationswhere continually exposed to water splash or spray.Poor insulation or swelling of the potting resin inside auto switchesmay cause malfunction.4. Do not use in an environment with oil or chemicals.Consult SMC if auto switches will be used in an environmentwith coolant, cleaning solvent, various oils or chemicals. If autoswitches are used under these conditions for even a short time,they may be adversely affected by improper insulation, malfunctiondue to swelling of the potting resin, or hardening of thelead wires.5. Do not use in an environment with temperaturecycles.Consult SMC if switches are used where there are temperaturecycles other than normal temperature changes, as they may beadversely affected internally.6. Do not use in an environment where there is excessiveimpact shock.When excessive impact (300 m/s 2 or more) is applied to a reedswitch during operation, the contact point will malfunction andgenerate or cut off a signal momentarily (1 ms or less). ConsultSMC regarding the need to use a solid state switch dependingupon the environment.7. Do not use in an area where surges are generated.When there are units (solenoid type lifter, high-frequency inductionfurnace, motor, etc.) which generate large surges in thearea around actuators with solid state auto switches, this maycause deterioration or damage to the auto switches. Avoidsources of surge generation and crossed lines.Back page 4

Series MK/MK2/MK2TAuto SwitchesPrecautions 4Be sure to read this before handling.CautionOperating Environment1. Avoid accumulation of iron debris or close contactwith magnetic substances.When a large amount of ferrous debris such as machiningchips or spatter is accumulated, or a magnetic substance (somethingattracted by a magnet) is brought into close proximitywith an auto switch actuator, it may cause the auto switch (actuator)to malfunction due to a loss of the magnetic force insidethe actuator.2. Consult SMC concerning water resistance, elasticityof lead wires, usage at welding sites, etc.3. Do not use in direct sunlight.4. Do not mount the product in locations where it is exposedto radiant heat.MaintenanceWarning1. Perform the following maintenance periodically inorder to prevent possible danger due to unexpectedauto switch malfunction.1) Securely tighten auto switch mounting screws.If screws become loose or the mounting position is dislocated,retighten them after readjusting the mounting position.2) Confirm that there is no damage to lead wires.To prevent faulty insulation, replace auto switches or repairlead wires, etc., if damage is discovered.3) Confirm the lighting of the green light on the 2-colour indicatortype auto switch.Confirm that the green LED is on when stopped at the establishedposition. If the red LED is on, the mounting position isnot appropriate. Readjust the mounting position until thegreen LED lights up.2. Maintenance procedures are outlined in the operatingmanual.Not following proper procedures could cause the product tomalfunction and could lead to damage to the equipment or machine.3. Removal of equipment, and supply/exhaust of compressedairBefore any machinery or equipment is removed, first ensurethat the appropriate measures are in place to prevent the fall orerratic movement of driven objects and equipment, then cut offthe electric power and reduce the pressure in the system to zero.Only then should you proceed with the removal of any machineryand equipment.When machinery is restarted, proceed with caution after confirmingthat appropriate measures are in place to prevent actuatorsfrom moving suddenly.Back page 5
