Pro-Range CZJ-A30-25ANA Inductive Proximity Sensor - NPN Output, M30 Thread, 25mm Detection

The CZJ-A30-25ANA typically operates on a 10-30V DC supply. It is crucial to stay within this range and ensure correct polarity connection, as the built-in protection safeguards against reverse voltage but does not enable operation outside the specified limits.

Connect the sensor's brown wire (+V), blue wire (0V/GND), and black wire (NPN output signal) to your system. The NPN output acts as a switch to ground (sinking); when a target is detected, the black wire pulls low (near 0V), which is read as a logic '1' or 'ON' state by most PLC DC input modules.

While primarily optimized for ferrous metals like steel, inductive sensors can detect non-ferrous metals, but the effective sensing distance will be significantly reduced, often by 30-50%. For reliable operation, it is recommended to test with the specific target material and adjust the installation distance accordingly.

Use a standard M30 locknut or mount the sensor directly into a tapped M30 x 1.5mm hole in your machine frame. Ensure the sensing face is flush and unobstructed. Maintain the specified lateral and axial clearance distances from other metal objects to prevent false triggering or reduced sensitivity.
