Autonics PRW12-4DN M12 4mm NPN Inductive Proximity Sensor
Metal Detection for Machine Control
The Autonics PRW12-4DN detects metal targets without physical contact. Its 4 mm sensing distance suits compact machine installations. The NPN normally open output switches on when a target enters the sensing zone.

Installation and Electrical Protection
Keep the sensing face clear of surrounding metal during non-flush installation. The cable connector allows disconnection during maintenance. A red LED shows operating status. Built-in protection covers reverse polarity, surges and output short-circuit overcurrent.
Application Areas
Typical uses include metal part detection on assembly lines, position monitoring in machine tools and component counting on conveyors. Packaging machinery can use the sensor to detect metal carriers or mechanical reference points.
FAQ
Q1: Can it detect plastic parts directly?
A: No. It is designed for metal detection.
Q2: Is the 4 mm range identical for every metal?
A: No. The rated distance uses an iron target. Other metals may reduce the range.
Q3: Can the sensing face be mounted flush in metal?
A: No. This model requires non-flush installation.
Q4: What PLC input does it require?
A: An input compatible with an NPN sinking output.
