Inductive proximity sensor PL-05N NPN 10-30VDC and its properties
The PL-05N NPN 10-30VDC Inductive Proximity Sensor from OMCH can detect metal objects approaching the sensor without physical contact with the target. A coil in an oscillating circuit creates a high-frequency magnetic field. When the target approaches the magnetic field, an induction current ("eddy current") flows in the target due to electromagnetic induction. As the target approaches the sensor, the induction current increases, causing an increase in impedance in the oscillating circuit. Then the oscillation weakens or stops. The sensor detects this change in state of oscillation based on the change in the sensed amplitude.
This sensor is of the "normal open" (NO) type, which means that the output is switched on only when the target enters the detection area. The output is in the normal state "off".
