Pro-Range CCJ-A30-15ANB Capacitive Proximity Sensor NPN M30 Thread 15mm Detection

The Pro-Range CCJ-A30-15ANB is designed for a standard industrial DC voltage range of 10 to 30V DC. Ensure your power supply is within these limits and properly fused for safe operation with the sensor's built-in polarity protection.

The NPN output is a sinking type. Connect the brown wire to DC+, blue to DC-, and the black output wire to your PLC's digital input. The sensor will pull the input to ground (DC-) when an object is detected, completing the circuit if your PLC input is internally pulled up to DC+.

While capacitive sensors are primarily optimized for non-metallic materials like plastics, liquids, and powders, they can detect conductive objects if the sensitivity is adjusted appropriately. However, for reliable metal detection, an inductive proximity sensor is typically the recommended choice.

A sensitivity adjustment potentiometer is located on the rear or side of the sensor housing. Use a small screwdriver to turn it. Increase sensitivity (clockwise) to detect lower-dielectric materials or objects farther away; decrease it (counter-clockwise) to avoid false triggers from background objects or environmental factors.

Yes, the M30 x 1.5mm thread is a standard metric size. For optimal performance, mount the sensor using a matching locknut, ensuring the sensing face is flush with or slightly recessed in the mounting surface. Avoid mounting near metal objects within the lateral sensing field to prevent interference.
