Pro-Range CLJ-A12M-2ANB NPN Inductive Proximity Sensor 2mm Detection - M12 Thread

The sensor typically operates from a 6-36V DC supply. It is crucial to stay within this range and ensure correct polarity connection, as the built-in protection safeguards against reverse voltage and short-circuits but does not compensate for sustained over-voltage.

The NPN output is a sinking switch. Connect the sensor's brown wire (+V), blue wire (0V/GND), and black wire (signal output) to your system. The black wire will pull the PLC input to ground (sink current) when a target is detected. Always refer to the controller's manual for specific input sink/source requirements.

Yes, inductive sensors detect all conductive metals, but the effective sensing distance is reduced for non-ferrous metals compared to steel. For the CLJ-A12M-2ANB, the 2mm nominal distance is specified for mild steel; for aluminum, expect a reduction factor, typically to approximately 60-70% of the rated distance.

Use a standard M12 locknut and washer. Install the sensor by threading it into a pre-tapped M12 hole in your mounting bracket or machine frame. Ensure the sensing face is flush and unobstructed, and maintain the specified lateral and frontal clearance from other metal objects to prevent false triggering.
