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

This sensor is designed to detect non-metallic objects such as plastics, glass, wood, cardboard, liquids, powders, and granular materials. It senses changes in dielectric constant, making it unsuitable for purely metallic targets, which are better detected by inductive sensors.

Connect the brown wire to +24V DC, the blue wire to 0V (common), and the black wire to your PLC's digital input. The black (output) wire will source current (provide +24V) when an object is detected. Ensure your PLC input is configured for PNP (sourcing) signals and includes a pull-down resistor if necessary.

Yes, the sensor features a sensitivity adjustment potentiometer. Turning it clockwise increases sensitivity and effective detection distance, while counter-clockwise rotation decreases it. This allows tuning for different material densities and to avoid false triggers from background objects.

The sensor operates from 10 to 30V DC. It includes built-in protection against short-circuit, overload, and reverse polarity connection, enhancing its durability and reliability in industrial environments with potential wiring mistakes or electrical noise.

With its IP67 rating and threaded M30 metal housing, the sensor is sealed against dust ingress and protected from temporary immersion in water up to 1 meter for 30 minutes. It is well-suited for washdown areas, food processing, and outdoor industrial applications.
