Pro-Range CZJ-A30M-16APA Inductive Proximity Sensor, PNP Output, 16mm Detection, M30 Thread

The CZJ-A30M-16APA sensor operates from 10 to 30 Volts DC. It is designed for compatibility with standard 24V DC industrial control systems and includes reverse polarity protection to prevent damage from incorrect wiring.

No. This is an inductive proximity sensor, which works by detecting changes in an electromagnetic field caused by conductive materials. It can only detect metallic objects (both ferrous and non-ferrous metals). Non-conductive materials like plastic, wood, or glass will not be detected.

Connect the brown wire to the positive DC supply (10-30V), the blue wire to the DC common (0V), and the black wire to the PLC digital input. The PNP output sources current from the black wire to the PLC input when a metal target is detected. Always refer to the controller's manual for specific sink/source input compatibility.

The nominal sensing distance is 16mm for a standard mild steel target. The effective distance can be reduced for non-ferrous metals like aluminum or copper, typically by a factor of 0.3 to 0.8. For precise positioning, always test with the actual target material.

The stainless steel M30 housing provides robust environmental sealing, typically equivalent to IP67. This makes it resistant to dust ingress and temporary immersion, suitable for many industrial environments. However, for continuous high-pressure washdown or corrosive chemical exposure, a sensor with a specific IP69K rating should be considered.
