Perform thorough alignmentand assure that excessiveforce is not applied to thefingers during the workpiece gripping operation.Particularly when performing a trial run,operation should be done manually orwith low cylinder pressure and speed,while confirming that there is no impactor other unsafe conditions.Aligned4. Adjust with a device suchas a speed controller sothat the finger closingspeed and push rod extension/retractionare no fasterthan necessary.If the finger closing speed and thepush rod extension/retraction speedare greater than necessary, impactforces acting on the fingers and otherparts will increase. This will cause adanger of poor work piece gripping repeatabilityand an adverse effect onservice life.Applicable speed controllersAir gripper directcoupling type: AS1200, M3, M5AS2200-01, etc.In-line type: AS1000 SeriesAS1001F, AS2051F, etc.PipingCautionImpact loadNot aligned1. Preparation before pipingBefore piping is connected, it should bethoroughly blown out with air (flushing)or washed to remove chips, cutting oiland other debris from inside the pipe.2. Wrapping of pipe tapeWhen screwing together pipes and fittings,etc., be certain that chips fromthe pipe threads and sealing materialdo not get inside the product.Also, when pipe tape is used, leave 1.5to 2 thread ridges exposed at the endof the threads.Operating EnvironmentWarning1. Do not operate in locationshaving an atmosphere of corrosivegases, chemicals, seawater, water, water vapor, orwhere contact with any ofthese may occur.2. Provide shading in locationswhich receive direct sunlight.3. Do not use in locations wherevibration or impact occurs.4. Do not use in locationswhere radiated heat will bereceived from nearby heatsources.5. Attach a cover or other protectionin locations wherethere will be exposure to dustor cutting oil.6. Contact SMC before using inan environment where adverseeffects appear particularlylikely.LubricationCaution1. The non-lube type air gripperis lubricated at the factory,and can be used withoutany further lubrication.In the event that lubrication will be applied,use Class 1 turbine oil (withoutadditives) ISO VG32. Furthermore,once lubrication is applied, it must becontinued.If lubrication is later stopped, malfunctioncan occur due to loss of the originallubricant.MaintenanceWarning1. Do not allow people to enteror place objects into the carryingpath of the air gripper.This can cause injury or accidents, etc.2. Do not put hands, etc., inbetween the air gripper fingersor attachments.This can cause injury or accidents, etc.3. When removing the air gripper,first confirm that nowork pieces are being heldand then release the compressedair before removingthe air gripper.If a work piece is still being held, thereis a danger of it being dropped.

Warning1. Confirm the specifications.Read the specifications carefully anduse this product appropriately. Theproduct may be damaged or malfunctionif it is used outside the range of specificationsfor load current, voltage, temperatureor impact.2. Take precautions whenmultiple air grippers areused close together.When multiple auto switch air grippersare used in close proximity, magneticfield interference may cause the switchesto malfunction. Maintain a minimumair gripper separation of 40mm. (Whenthe allowable separation is indicated foreach air gripper series, use the specifiedvalue.)3. Pay attention to the lengthof time that a switch is ONat an intermediate strokeposition.When an auto switch is placed at anintermediate position of the stroke and aload is driven at the time the pistonpasses, the auto switch will operate, butif the speed is too great the operatingtime will be shortened and the load maynot operate properly. The maximumdetectable piston speed is:Auto switch operating range (mm)V(mm/s) =Load operating time (ms)4. Keep wiring as short aspossible.Although wire length should not affectswitch function, use a wire 100m orshorter.5. Take precautions for the internalvoltage drop of theswitch.Generally, the internal voltage drop willbe greater with a 2 wire solid state autoswitch than with a reed switch.Series MHSAuto Switch Precautions 1Be sure to read before handling.• Take note that there will be a large voltagedrop if auto switches are connectedin series as shown below. (Refer to internalvoltage drop in the auto switch specifications.)[The voltage drop will be "n" times largerwhen "n" auto switches are connected.]Design and Selectionx 1000Even though an auto switch operatesnormally, the load may not operate.• In the same way, when operating at orbelow a specified voltage, although anauto switch may operate normally, theload may not operate. Therefore, theformula below should be satisfied afterconfirming the minimum operatingvoltage of the load.Supply voltage – Internal voltage>drop of switchAlso, note that a 12VDC relay is not applicable.6. Pay attention to leakagecurrent.With a 2 wire solid state auto switch,current (leakage current) flows to theload to operate the internal circuit evenwhen in the OFF state.Operating current of load(OFF condition)LoadMinimum operatingvoltage of load> Leakage currentIf the criteria given in the above formulaare not met, it will not reset correctly(stays ON). Use a 3 wire switch if thisspecification will not be satisfied.Moreover, leakage current flow to theload will be "n" times larger when "n"auto switches are connected in parallel.7. Do not use a load that generatessurge voltage.Although a zener diode for surge protectionis connected at the output side of asolid state auto switch, damage may stilloccur if the surge is applied repeatedly.When a load, such as a relay or solenoid,which generates surge is directlydriven, use a type of switch having abuilt-in surge absorbing element.8. Cautions for use in aninterlock circuit.When an auto switch is used for an interlocksignal requiring high reliability,devise a double interlock system toavoid trouble by providing a mechanicalprotection function, or by also usinganother switch (sensor) together withthe auto switch. Also perform periodicmaintenance and confirm proper operation.9. Ensure sufficient clearancefor maintenance activities.When designing an application, be sureto allow sufficient clearance for maintenanceand inspections.Mounting & AdjustmentWarning1. Do not drop or bump.Do not drop, bump or apply excessiveimpacts (1000m/s² or more for solidstate switches) while handling.Although the body of the switch may notbe damaged, the inside of the switchcould be damaged and cause a malfunction.2. Do not carry a cylinder bythe auto switch lead wires.Never carry a cylinder by its lead wires.This may not only cause broken leadwires, but it may cause internal elementsof the switch to be damaged bythe stress.3. Mount switches using theproper tightening torque.When a switch is tightened beyond therange of tightening torque, the mountingscrews, mounting bracket or switch maybe damaged. On the other hand, tighteningbelow the range of tighteningtorque may allow the switch to slip out ofposition. (Refer to pages 59 through 65regarding switch mounting, movementand tightening torque, etc.)WiringWarning1. Avoid repeatedly bendingor stretching lead wires.Broken wires will result from applyingrepeated bending stress or stretchingforce to the lead wires.2. Be sure to connect the loadbefore power is applied.If the power is turned ON when an autoswitch is not connected to a load, theswitch will be instantly damagedbecause of excess current.3. Confirm proper insulationof wiring.Be certain that there is no faulty wiringinsulation (contact with other circuits,ground fault, improper insulationbetween terminals, etc.). Damage mayoccur due to excess current flow into aswitch.4. Do not run wiring nearpower lines or high voltagelines.Wire separately from power lines or highvoltage lines, avoiding parallel wiring orwiring in the same conduit with theselines. Control circuits containing autoswitches may malfunction due to noisefrom these other lines.742 finger MHS2 3 finger MHS3With dust coverMHSJ3Through holeMHSH3Long strokeMHSL34 finger MHS4 Auto switchesModel selectionPrecautions

Avoid incorrect wiring.1) If connections are reversed on a 2 wiretype switch, the switch will not be damagedif protected by a protection circuit,but the switch will always stay in an ONstate. However, it is still necessary toavoid reversed connections, since theswitch could be damaged by a loadshort circuit in this condition.Wiring2) If connections are reversed (power supplyline + and power supply line –) on a3 wire type switch, the switch will be protectedby a protection circuit. However, ifthe power supply line (+) is connected tothe blue wire and the power supply line(–) is connected to the black wire, theswitch will be damaged.Operating EnvironmentWarning Warning WarningOldPower supply (+) RedPower supply GND BlackOutputWhiteLatch type diagnosticoutputYellowOrange1. Never use in an atmosphereof explosive gases.The structure of auto switches is notintended to prevent explosion. Neveruse in an atmosphere with an explosivegas since this may cause a seriousexplosion.2. Do not use in an area wherea magnetic field is generated.Auto switches will malfunction or magnetsinside air grippers will become demagnetized.3. Do not use in an environmentwhere the autoswitch will be continuallyexposed to water.Although switches, except for a fewmodels, conform to IEC standard IP67construction (JIS C 0920: watertightconstruction), avoid using switches inapplications where continually exposedto water splash or spray. Poor insulationor swelling of the potting resin insideswitches may cause malfunction.4. Do not use in an environmentwith oil or chemicals.Consult SMC if auto switches will beused in an environment with coolant,cleaning solvent, various oils or chemicals.If auto switches are used underthese conditions for even a short time,they may be adversely affected byimproper insulation, malfunction due toswelling of the potting resin, or hardeningof the lead wires.5. Do not use in an environmentwith temperaturecycles.Consult SMC if switches are used wherethere are temperature cycles other thannormal air temperature changes, as theymay be adversely affected internally.75

Series MHSAuto Switch Precautions 3Operating EnvironmentWarningBe sure to read before handling.6. Do not use in locationswhere surge is generated.When there are units (solenoid type lifter,high frequency induction furnace, motor,etc.) which generate a large amount ofsurge in the area around air grippers withsolid state auto switches, this may causedeterioration or damage to the switches.Avoid sources of surge generation anddisorganized lines.7. Avoid accumulation of irondebris or close contact withmagnetic substances.When a large amount of ferrous debrissuch as machining chips or spatter isaccumulated, or a magnetic substance(something attracted by a magnet) isbrought into close proximity with an autoswitch air gripper, it may cause the autoswitch to malfunction due to a loss ofthe magnetic force inside the air gripper.MaintenanceWarning1. Perform the followingmaintenance periodicallyin order to prevent possibledanger due to unexpectedauto switch malfunction.1) Securely tighten switch mountingscrews.If screws become loose or the mountingposition is dislocated, retighten themafter readjusting the mounting position.2) Confirm that there is no damage to leadwires.To prevent faulty insulation, replaceswitches or repair lead wires, etc., ifdamage is discovered.3) Confirm lighting of the green light on 2color indication type switches.Confirm that the green LED is on whenstopped at the established position. Ifthe red LED is on, the mounting positionis not appropriate. Readjust the mountingposition so that the green LED lightsOtherWarning1.
