SMART SWITCHS E R I E S600DESCRIPTIONThe NOSHOK Smart Switch is truly a “State of the Art”pressure switch. It’s design is based upon our proven sputtered thinfilm and diffused semiconductor pressure transmitters for unparalleledaccuracy, stability, overpressure protection and service life. Switching isaccomplished digitally by means of an internal signal conditioner whichmeans there are never any mechanical contacts to wear out. They areavailable with either one or two switch functions of either PNP (positive)output or NPN (negative) output in either N.O. (normally open) or N.C.(normally closed) configurations.Because the adjustments are made digitally; set points andhysteresis are fully adjustable and completely tamperproof.Programming can be done at the factory or in the field by means ofa PC running Windows and using the NOSHOK Smart Switch softwareand programming hardware.All wetted areas are 316 SS and are welded with no o-rings, gasketsor seals to leak or fail.Available pressure ranges are from 0-5 psig through 15,000 psigincluding vacuum, compound and absolute ranges.They also process the highest EMC capabilities along with thehighest mechanical shock and vibration resistance available anywhere.When only the best will do, the NOSHOK Smart Switch is theonly choice.FEATURESMeasuring ranges from 5 psi through 15,000 psi includingvacuum, compound and absolute.Corrosion resistant 316 SS welded constructionSingle or Dual switch setpoint functionsN.O. or N.C. switching functionsPositive or negative switching capabilityProgrammable, tamperproof setpointsHigh overpressure protectionHighly resistant to mechanical shock and vibrationHigh EMC capabilitiesAPPLICATIONSHydraulic and pneumatic systemsIndustrial machinery and machine toolsMolding and extruding equipmentStamping and forming pressesPumps and compressorsLaboratory and test equipmentHVACPower generationRefrigerationConstruction equipmentMedicalTransportation equipmentWater management MarinePetrochemicalPressure RangesSPECIFICATIONS0-5 psi through 0-15,000 psi including vacuum, compoundand absoluteProof Pressure ≤ 200 psi: 3.5x , 300-10,000 psi: 2x , above 10,000 psi: 1.5xProcess ConnectionWetted PartsCase1/4″ NPT standard; 1/2″ NPT optional316 SS304 SSSwitching Functions 1 or 2N.O. or N.C.p-or n-switchingAdjustment Switching point 0...100% of F.S.Hysteresis 1...99% of F.S.Dampening 0...500msAccuracyRepeatabilityStability per YearPower Supply≤ 1% of F.S.

S E R I E S40.1MAGNETIC SPRING CONTACT SWITCHNOSHOK Magnetic Spring Contact Switches (MSCS) are anexcellent choice when an accurate pressure switch is requiredin addition to a high quality reliable pressure gauge.These magnetic spring contact switches are fully adjustableby the user with the advantage of accurate field adjustmentbecause they are actuated by the pressure gauge pointer.A removable adjustment key also makes them tamper proof.They operate with an extremely broad power supply, AC orDC up to 250V max. This feature allows them to be used virtuallyanywhere in the world in addition to very remote applicationswith only DC battery pack power available.The standard units consist of (2) two magnetic spring contactswitches. Switch (1) one is normally closed and switch (2) two isnormally open with operation referenced on rising (or increasing)pressure. Either one or both switches may be used.Magnetic spring contact switches are available as a factoryinstalled option on models 40.105, 40.115, 40.400 and 40.410.The lowest full scale pressure range it may be used on is0-60 PSI because of the increased load on the pointer andbourdon tube.Typical applications include air compressors, gas compressors,hydraulic and pneumatic circuitry, die-cast machinery, plasticinjection molding machinery and anywhere accurate off/onswitching capabilities based on pressure are required.The NOSHOK MSCS is pre-wired with a matching 4-pinconnector in its standard configuration with 5 feet of 4-wire, colorcoded shielded cable..48″(12.2mm)1.81″(46mm)3.40″(86.4)MAGNETIC SPRING CONTACT SWITCHCONTACT NO. 1Normally Closed,Opens on RisingPressureCONTACT NO. 2Normally Open,Closes on RisingPressureSPECIFICATIONSType of PowerMaximum AmpsA.C. or D.C. 24 to 250V max1.0 AMaximum Switching30W/50 VACapacityGauge Accuracy Add an additional ± 2% Error on Full Scale Ranges of 0-160PSI and above.
