Pro-Range CZJ-A18-16APA Inductive Proximity Sensor - PNP Output, M18 Thread, 16mm Detection

This 3-wire PNP sensor follows the standard industrial color code: connect the brown wire to the positive DC supply (10-30V), the blue wire to the power supply ground (0V), and the black wire is the switched PNP output signal. The output will switch to supply voltage (+V) when a metal target is detected within the 16mm range.

Yes, inductive proximity sensors can detect all conductive metals, but the sensing distance is reduced for non-ferrous metals compared to steel. For this 16mm-rated sensor, the effective sensing distance for aluminum is typically 40-60% of the rated value (approximately 6-10mm). Always verify detection with the actual target material.

PNP (sourcing) outputs switch the positive voltage to the load, while NPN (sinking) outputs switch the ground connection. PNP is commonly used with PLCs that have a common negative input. Ensure your controller's input type (sinking or sourcing) matches the sensor's output to avoid connection issues or damage.

For optimal performance, mount the sensor using the provided M18 nuts. Ensure the sensing face is flush and unobstructed. Maintain a clearance of at least one sensor diameter from any surrounding metal to prevent false triggering. The sensing distance is rated for a standard steel target; use the actual target material for final positioning tests.
