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

The CZJ-A30-25APB has a PNP (sourcing) output. This means the output switch connects the signal line to the positive supply voltage when activated. It is typically used with PLCs and controllers that require a positive voltage input signal. An NPN (sinking) output, in contrast, would connect the signal line to ground.

This sensor detects both ferrous metals (like iron and steel) and non-ferrous metals (like aluminum, copper, and brass). The exact sensing distance may vary slightly depending on the target material's conductivity and permeability, with ferrous metals typically providing the longest detection range.

Connect the brown wire to the positive DC supply voltage (e.g., +24V), the blue wire to the DC common (0V), and the black wire is the PNP output signal. When a metal target is detected, the black wire will source voltage (e.g., +24V) to your controller's input. Always ensure the load (e.g., PLC input) is connected between the black wire and the DC common.

While the M30 threaded housing provides robust mechanical sealing, the specific IP rating is not provided in the datasheet. For outdoor or wet environments, it is recommended to consult the manufacturer's official specifications for the IP (Ingress Protection) rating or use an additional protective enclosure to prevent water and dust ingress.
