Pro-Range CZJ-A12-8ANB NPN Inductive Proximity Sensor, 8mm Detection Distance, M12 Thread

This sensor has an NPN (sinking) output. The wiring typically involves connecting the brown wire to the positive DC supply (10-30V), the blue wire to the negative/common ground, and the black wire as the signal output. When activated, the black wire switches to ground (sinks current). Always refer to the specific datasheet for the exact wiring diagram and pinout.

It can detect both ferrous (like iron and steel) and non-ferrous (like aluminum, copper, brass) metals. However, the sensing distance may vary depending on the target material's conductivity and permeability; ferrous metals are typically detected at the full nominal range (8mm), while non-ferrous metals may have a reduced effective sensing distance.

Yes, but an interface circuit is required. The sensor's output is a switched ground signal relative to its own supply voltage. You will need to use a voltage divider or an opto-isolator module to safely translate the sensor's higher voltage output (up to 30V) down to the 5V or 3.3V logic level compatible with Arduino or Raspberry Pi GPIO pins.

Inductive sensors of this type typically operate on a DC supply voltage range of 10-30V. The current draw is usually low, in the range of 10-20mA when active. Always confirm with the official Pro-Range datasheet for the CZJ-A12-8ANB model's exact electrical specifications before finalizing your system design.
