Pro-Range CZJ-A8M-2APB PNP Inductive Proximity Sensor - M8 Thread, 2mm Detection

The CZJ-A8M-2APB is designed for a typical operating voltage range of 10 to 30V DC. It is compatible with standard 24V DC industrial control systems. Ensure your power supply is within this range and observe correct polarity, as the sensor includes reverse polarity protection.

No. This is an inductive proximity sensor, which operates by detecting changes in an electromagnetic field caused by conductive materials. It will only detect metallic objects, primarily ferrous metals like steel, and to a lesser extent, non-ferrous metals like aluminum or copper. Plastic, wood, and other insulators will not trigger the sensor.

Wire the brown (or red) wire to your DC positive supply (10-30V), the blue wire to DC negative (0V/GND), and the black wire is the PNP output. When a target is detected, the black wire will switch to supply voltage (sourcing). Connect the black wire to your PLC's digital input, which typically requires a connection to positive voltage to register a 'high' signal.

The 2mm value is the nominal sensing distance (Sn). This is the guaranteed operating distance for a standard target (usually a 1mm thick square of mild steel). The actual switching point may vary slightly due to target material, size, and environmental factors, and includes built-in hysteresis (typically 10-20% of Sn) to prevent output chatter.

Yes. The M8 threaded metal housing and epoxy-sealed construction provide a high degree of environmental sealing, typically equivalent to an IP67 rating. This makes it resistant to dust ingress and capable of withstanding temporary immersion in water, making it suitable for washdown areas and harsh industrial settings.
