Pro-Range CRJ-A30-15ANB Capacitive Proximity Sensor, NPN Output, M30 Thread, 15mm Detection

The sensor typically operates on a 10-30V DC supply. It is crucial to stay within this range to ensure proper switching of the NPN output and to avoid damage to the internal circuitry. Always verify your power supply compatibility before installation.

Yes, capacitive proximity sensors like the CRJ-A30-15ANB are specifically designed to detect both conductive and non-conductive materials. This includes plastics, glass, wood, granules, and liquids, making them ideal for level sensing and material handling applications where inductive sensors would fail.

A sensitivity adjustment potentiometer is located on the rear or side of the sensor housing. Use a small screwdriver to turn this potentiometer. Clockwise rotation generally increases sensitivity (lengthens detection range), while counter-clockwise rotation decreases it, allowing you to fine-tune performance for specific targets and to avoid false triggers.

The NPN output is a sinking configuration. When an object is detected, the output switch closes, connecting the output signal wire (typically black) to ground (0V). You must connect the load (e.g., a PLC input) between the positive supply voltage and this sensor output wire for it to function correctly.

While the stainless steel housing offers good corrosion resistance, the standard model is not specifically rated for waterproof or submersible use. For applications involving direct water spray, high humidity, or outdoor conditions, confirm the sensor's specific IP (Ingress Protection) rating or consider models explicitly designed for such environments.
