Pro-Range CRJ-A30-15APB Capacitive Proximity Sensor, PNP Output, M30 Thread, 15mm Detection

This capacitive sensor is designed to detect both metallic and non-metallic objects. It is particularly effective for materials that inductive sensors cannot detect, such as liquids, plastics, glass, wood, cardboard, and powders. The integrated sensitivity adjustment allows tuning for different material densities and container walls.

The PNP (sourcing) output connects the load (e.g., PLC input) between the sensor's output wire (typically brown or black) and the common negative (blue wire). The supply voltage (10-30V DC) is applied between the positive (brown) and negative (blue) wires. Always refer to the sensor's datasheet for the exact wiring diagram corresponding to your specific model and cable color code.

Yes, capacitive sensors like the CRJ-A30-15APB can detect material levels inside non-metallic containers. The sensing field penetrates materials like plastic or glass. The detection range and required sensitivity setting will depend on the wall thickness and the dielectric constant of both the container material and the target material inside.

The sensor operates from 10 to 30V DC, making it compatible with standard 12V and 24V industrial power supplies. It includes built-in reverse polarity protection, safeguarding the sensor if the power wires are accidentally connected backwards, and short-circuit protection on the output transistor to prevent damage from wiring faults.
