Pro-Range CLJ-C30-10ANA NPN Inductive Proximity Sensor 10mm Detection - 30x30mm Thread

The CLJ-C30-10ANA typically operates on a DC supply voltage range of 6 to 36V. Always connect the brown wire to positive voltage (+V) and the blue wire to ground (GND) as per standard 3-wire DC sensor convention. Ensure your power source can provide sufficient current for the sensor's internal circuitry and the load connected to its output.

The NPN output is an open-collector switch on the black wire. To interface with a PLC digital input or microcontroller, connect the black wire to your input pin. You must also connect a pull-up resistor (typically 1kΩ to 10kΩ) from that input pin to your logic voltage (e.g., 24V for PLCs, 5V/3.3V for microcontrollers). When the sensor detects a target, the NPN transistor turns on, pulling the output (black wire) low to GND.

This sensor is designed to detect conductive metals. It has optimal sensitivity for ferrous metals like steel (the standard 10mm range is specified for steel). It will also detect non-ferrous metals like aluminum, brass, and copper, but the effective sensing distance will be reduced, typically to 30-60% of the rated value. Non-metallic materials like plastic, wood, or glass will not be detected.

The M30 x 1.5mm threaded barrel housing allows for secure, adjustable mounting in a standard 30mm drilled hole on machine panels, brackets, or enclosures. The included nuts and bolts can be used to lock the sensor in position from the backside, preventing rotation or movement due to vibration. This standardized mounting facilitates easy installation and replacement in industrial settings.
