Pro-Range CLJ-A8-2APB NPN M8 Inductive Proximity Sensor - 2mm Detection

The CLJ-A8-2APB has an NPN (sourcing) output. In its normally open (NO) state, the output transistor switches the signal wire to ground (0V) when a target is detected. This is typically wired to a PLC's sinking input. A PNP sensor would switch the output to positive voltage (+V). Always verify your controller's input type before connecting.

This sensor is primarily designed to detect ferrous metals like steel and iron, providing the full 2mm nominal sensing distance. It can also detect non-ferrous metals like aluminum, brass, or copper, but the effective sensing distance will be significantly reduced, often by 30-60%, due to lower conductivity and permeability.

Typically, a 3-wire DC inductive sensor has Brown (+V), Blue (GND), and Black (Signal Output) wires. For this NPN model: connect Brown to +V DC (6-36V), Blue to 0V GND, and Black to your controller's input. The controller input must be configured as a sinking input, with an internal pull-up resistor to +V, to read the switch-to-ground signal.

Mount the sensor using its M8 x 1.0 metric thread directly into a tapped hole in a metal bracket or machine frame. Ensure the sensing face is flush with or slightly recessed from the mounting surface for accurate detection. Maintain the specified lateral and axial clearance around the sensor body to prevent false triggering from the mounting metal itself.
