Inductive Proximity Sensor

Inductive proximity sensors are used for non-contact detection of metallic objects. Their operating principle is based on a coil and oscillator that creates an electromagnetic field in the close surroundings of the sensing surface. The presence of a metallic object (actuator) in the operating area causes a dampening of the oscillation amplitude. The rise or fall of such oscillation is identified by a threshold circuit that changes the output of the sensor.Case material: Metal / CopperOuput Status: NOVoltage: 6-36VDCOutput Current: 300mAPolarity: NPNDimension: M12x1x55mmSize 6.2 x 2cm/2.4” x 0.8” (L*Max.
