Pro-Range CZJ-A12-8APA Inductive Proximity Sensor, 8mm Detection, PNP Output, M12 Thread

The CZJ-A12-8APA has a 3-wire PNP (sourcing) output. Connect the brown wire to your DC positive supply (typically 10-30V DC), the blue wire to DC negative (0V), and the black wire is the PNP output signal. When a metal target is detected, the black wire will source current to the positive supply voltage, switching your PLC or controller input high.

This sensor detects both ferrous (like steel and iron) and non-ferrous metals (like aluminum, brass, and copper). The sensing distance is standardized for mild steel. For non-ferrous metals, the effective detection range is reduced, typically by a factor (e.g., 0.4 to 0.8x), which must be accounted for during installation and positioning.

While not explicitly stated in the provided specs, standard Pro-Range inductive sensors in this series typically operate from 10-30V DC. The maximum load current for the PNP output is usually in the range of 100-200mA. Always verify with the specific datasheet for your application's voltage and current requirements before connection.

No. Inductive proximity sensors work on the principle of electromagnetic induction and can only detect conductive metallic objects. They will not detect insulating materials like plastic, wood, glass, or ceramics. For non-metallic object detection, you would need a capacitive proximity sensor.
