Pro-Range CZJ-A18-16ANA Inductive Proximity Sensor - NPN Output, M18 Thread, 16mm Detection

The Pro-Range CZJ-A18-16ANA is designed to operate within a 10 to 30 Volts DC range. It is compatible with standard 12V and 24V industrial control systems. Ensure correct polarity when connecting the brown wire to V+ and the blue wire to ground (0V).

The NPN output is a sinking type. Connect the black output wire to your PLC's digital input. The PLC input must be pulled high to its supply voltage (e.g., 24V) through an internal or external resistor. When the sensor detects metal, the NPN transistor sinks current, pulling the input low to signal detection.

Yes, inductive sensors can detect all conductive metals, but the sensing distance is reduced for non-ferrous materials. The 16mm nominal distance is specified for mild steel. For aluminum, expect an effective sensing distance of approximately 40-60% of the rated value, or around 6-10mm.

Use a standard M18 x 1.0 metric tap to create the mounting hole. The sensor should be mounted flush with or slightly recessed behind the mounting surface. Ensure no other metal objects are within the lateral sensing area (typically 1-2 times the sensor diameter) to avoid false triggering.

Yes, the module includes reverse polarity protection, preventing damage if power wires are accidentally swapped. It also features short-circuit protection on the output, safeguarding the internal switching transistor if the output is directly shorted to the positive supply rail.
