Pro-Range CZJ-A30-25APA Inductive Proximity Sensor - PNP Output, M30 Thread, 25mm Detection

Connect the brown wire to the positive DC supply (10-30V), the blue wire to the DC common (0V), and the black wire to your PLC digital input or load. The black wire (PNP output) will switch to supply voltage (+V) when a metal target is detected, sourcing current to the input. Always ensure the load is connected between the output and ground.

Yes, inductive sensors detect all conductive metals, but the sensing distance is reduced for non-ferrous materials. The rated 25mm distance is typically for mild steel (Fe360). For aluminum, copper, or brass, expect a reduction factor, often between 0.3 to 0.5, resulting in an effective range of approximately 7.5mm to 12.5mm. Always refer to the manufacturer's reduction factor chart for precise values.

PNP (sourcing) outputs switch the positive voltage to the load, commonly used with PLCs with sinking inputs in Europe and Asia. NPN (sinking) outputs switch the ground path. This sensor is PNP, meaning the signal wire (black) provides a positive voltage when active. Ensure your controller's input type (sinking vs. sourcing) is compatible with a PNP sensor to avoid incorrect operation.

With its IP67 rating, the sensor is protected against dust ingress and can withstand temporary immersion in water up to 1 meter for 30 minutes. It is suitable for damp industrial environments, washdown areas, and outdoor use if protected from direct, high-pressure water jets and prolonged submersion. For permanent underwater applications, an IP68 or IP69K rated sensor is required.
