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/DXDetection distance: 4mm10%Setting distance: 0-3.6mmDelay distance: <10% of detection distanceDetection object: Magnetic metal(The detection distance decreases when it is non-magnetic metal)Standard detection object: Iron 15*15*1mmResponse frequency: 0.5kHzSupply voltage: DC12-24V (6-36V) impulse (P-P) below 10%Withstand voltage: AC1000V 50/60Hz 1minCurrent consumption: N.P type: <13mA, D type: <0.8mA, A type: <1.7mAControl output: N.P type: <300mA, D type: <200mA, A type: <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%RHTemperature influence: Temperature range -30~65, at 23, 15% detection distance; Temperature range -25~60, at 23, 10% 0detection distanceInsulation impedance: >50MHousing material: Nickel plated brass Detection surface: ABSWeight: Approx. 80g/2.8ozPackage list:1 * Inductive Proximity Switch
