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

The sensor operates on a 10 to 30V DC supply. It is crucial to stay within this range to ensure proper function and avoid damage. The built-in polarity protection safeguards against accidental reverse connection.

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

A sensitivity adjustment potentiometer is located on the body of the sensor. Use a small screwdriver to turn it clockwise to increase sensitivity (detect objects further away) or counter-clockwise to decrease it. Adjust while observing the output LED to set the desired trigger point.

PNP (sourcing) output means the sensor switches the positive voltage to the load. In a typical wiring scheme, the sensor's brown wire connects to +V (10-30V DC), the blue wire to 0V (GND), and the black wire is the switched output that connects to your PLC input or relay. The load is connected between the black wire and GND.

Yes, this capacitive sensor is well-suited for detecting the level of non-conductive liquids (e.g., oil, water, chemicals) inside a non-metallic tank. The sensor can be mounted through the tank wall, and its sensitivity can be adjusted to reliably detect the presence or absence of the liquid at a specific point.
