Features:This is a normally close proximity switch sensor with 4mm detection distance.When proximity switch is close to some target object, it will send out control signal. It is a component widely used in automatic control industry for detecting, controlling, and non-contact switching. High sensitivity, quick response, stable performance.Non-contact detection avoids the sensor and the target object from damages.Specification:Model: LJ12A3-4-Z or DXDetection distance: 4mm10 percent Setting distance: 0-3.6mmDelay distance: andlt 10 percent of detection distanceDetection object: Magnetic metal(The detection distance decreases when it is non-magnetic metal)Standard detection object: Iron 15x15x1mmResponse frequency: 0.5kHzSupply voltage: DC12-24V (6-36V) impulse (P-P) below 10 percent Withstand voltage: AC1000V 50 or 60Hz 1minCurrent consumption: N.P type: andlt 13mA, D type: andlt 0.8mA, A type: andlt 1.7mAControl output: N.P type: andlt 300mA, D type: andlt 200mA, A type: andlt 400mALoop protection: N.P.D type: reverse connection protection, surge absorption, load short circuit protection, type A: surge absorptionAmbient temperature and humidity: -30-65, 35-95 percent RHTemperature influence: Temperature range -30-65, at 23, 15 percent detection distance Temperature range -25-60, at 23, 10 percent 0detection distanceInsulation impedance: andgt 50MHousing material: Nickel plated brass Detection surface: ABSWeight: Approx. 80g or 2.8ozPackage list:1 x Inductive Proximity Switch
