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 distance 4mm ± 10% set distance 0-3.6mm Delay distance < 10% detection distance Detection of objects Magnetic metal (decreased detection distance for non-magnetic metal) Standard test object iron 15*15*1mm Response frequency DC:0.5kHz AC:25Hz power supply voltage DC:DC12-24V(6-36V)pulse（P-P）10%Below Withstand voltage AC1000V 50/60Hz 1min Between the charging part and the enclosure Voltage effect Rated power supply voltage range within ±15%, when rated power supply voltage value within ±10% detection distance Current consumption N.P type:13mA below,D type:0.8mA below,A type:1.7mA below Control output N.P type:300mA below,D type:200mA below,A type:400mA below Circuit protection N.P.D type:Reverse connection protection, surge absorption, load short circuit protection, type A: surge absorption Ambient temperature and humidity Activity, save: each - 30 ~+ 65 ℃ (no ice, no frost), action time, save time: each 35-95% RH Temperature effect Temperature range-30~65℃, at 23 ℃, ±15% detection distance within Temperature range - 25 ~ 60 ℃ , at 23 ℃, ± 10% detection distance within Insulation impedance More than 50 m Ω (DC500 megger) charge between parts and the shell material Case: brass plated nickel detection surface: ABS Weight 46 g / 1.6 oz(approx.)
