Pro-Range CCJ-A30M-10APB Capacitive Proximity Sensor PNP M30 Thread 10mm Detection

The CCJ-A30M-10APB is designed for a typical industrial DC voltage range of 10-30V. Ensure your power supply is within these limits and correctly polarized, as the sensor includes reverse polarity protection but requires proper voltage for reliable operation.

While primarily optimized for non-metallic materials like plastics, liquids, and glass, capacitive sensors can detect conductive objects. However, detection distance and stability may vary compared to dedicated inductive sensors. For reliable metal detection, an inductive proximity sensor is recommended.

A built-in potentiometer, typically accessed via a small screwdriver slot on the sensor body, allows you to adjust the detection threshold. Turn it clockwise to increase sensitivity (detect objects further away) and counter-clockwise to decrease it, helping to avoid false triggers from the background or container walls.

The standard 3-wire configuration is: Brown wire to DC positive (+V), Blue wire to DC negative (0V/GND), and Black wire is the PNP output. When a target is detected, the Black wire switches to supply +V (sourcing) to the load, which should be connected between the Black wire and 0V.
