Pro-Range CZJ-A18M-8APA Inductive Proximity Sensor PNP Output, M18 Thread, 8mm Detection

This 3-wire DC sensor follows the standard color code: Brown wire connects to the positive supply voltage (10-30V DC), Blue wire connects to the common ground (0V), and the Black wire is the PNP output signal. When a target is detected, the Black wire switches to supply voltage (sourcing). Always connect a pull-down resistor at the PLC input if required by your controller.

Yes, inductive sensors detect all conductive metals, but the effective sensing distance is reduced for non-ferrous materials. The 8mm nominal distance is specified for mild steel (Fe360). For aluminum, copper, or stainless steel, you should derate the sensing distance, typically to 60-80% of the nominal value, and perform application testing.

PNP (sourcing) output switches the positive voltage to the load, commonly used with PLC sinking inputs in Europe and many global standards. NPN (sinking) output switches the ground path. This sensor is a PNP type. Ensure your controller's digital input is compatible with a sourcing (PNP) signal before installation.

Inductive proximity sensors like the CZJ-A18M-8APA have fast response times, typically under 1 ms. The maximum switching frequency is approximately 500 Hz, allowing detection of up to 500 targets per second. This makes it suitable for high-speed counting and position sensing on fast-moving machinery.
