Pro-Range CLJ-A12M-2ANA Inductive Proximity Sensor, Detection Distance 2mm - NPN Output, M12 Thread

The sensor is designed for a typical DC supply voltage range of 10-30V. Always connect the brown wire to positive voltage and the blue wire to ground. Exceeding this range may damage the internal circuitry.

No, this is an inductive proximity sensor, which operates by detecting changes in an electromagnetic field. It is specifically designed to detect ferrous metals like steel and iron. Non-conductive materials such as plastic, wood, or glass will not be detected.

The NPN output provides a switched ground signal. Connect the black output wire to your PLC's digital input. The PLC input should be pulled high internally or via an external resistor. When a metal target is detected, the sensor connects the black wire to ground (blue wire), pulling the PLC input low.

The 2mm nominal detection distance is the standard sensing range for a standard steel target (typically a 1mm thick square of iron). The actual sensing distance can vary by approximately ±10% and may be slightly less for non-ferrous metals like aluminum. Ensure the target approaches the sensor face axially for reliable operation.

While the brass housing provides good durability, the standard IP rating for this sensor type is typically IP67, meaning it is dust-tight and can withstand temporary immersion. For permanent outdoor installation or continuous water exposure, verify the specific IP rating and consider additional protective enclosures.
