Features:Proximity switch is a position sensor with switch output that can be connected with microcomputer It also can drive directly from, electromagnetic relays, counters and contactor to achieve automatic control purposes It is a component widely used in automatic control industry for detecting, controlling, and non-contact switching. When proximity switch is close to some target object, it will send out control signal. It's widely used in machine, paper making, light industry for limiting station, orientation taking count, speeding trial etc. Specification:Detection distance4mm 10%set distance0-3.6mmDelay distance < 10% detection distanceDetection of objectsMagnetic metal (decreased detection distance for non-magnetic metal)Standard test objectiron 15*15*1mmResponse frequencyDC:0.5kHz AC:25Hzpower supply voltageDC:DC12-24V(6-36V)pulseP-P10%BelowWithstand voltageAC1000V 50/60Hz 1min Between the charging part and the enclosureVoltage effectRated power supply voltage range within 15%, when rated power supply voltage value within 10% detection distanceCurrent consumptionN.P type:13mA below,D type:0.8mA below,A type:1.7mA belowControl outputN.P type:300mA below,D type:200mA below,A type:400mA belowCircuit protectionN.P.D type:Reverse connection protection, surge absorption, load short circuit protection, type A: surge absorptionAmbient temperature and humidityActivity, save: each - 30 ~+ 65 (no ice, no frost), action time, save time: each 35-95% RHTemperature effectTemperature range-30~65, at 23 , 15% detection distance withinTemperature range - 25 ~ 60 , at 23 , 10% detection distance withinInsulation impedanceMore than 50 m (DC500 megger) charge between parts and the shellmaterialCase: brass plated nickel detection surface: ABSWeight46 g / 1.6 oz(approx.)Package list:1 x Proximity sensor
