A. Product Overview

The Autonics PRWL08-1.5DN is a compact cylindrical inductive proximity sensor designed for detecting metallic targets without physical contact.

It belongs to the PRWL Series and uses an M8 cylindrical threaded body with a long body design and cable connector configuration. The sensor provides a 1.5 mm sensing distance and uses an NPN normally open control output.

The flush mounting design allows the sensing head to be installed into suitable metallic mounting structures while maintaining the recommended installation clearances.

Its 1.5 kHz response frequency makes the sensor suitable for relatively fast repetitive detection applications.

B. Working Principle

The Autonics PRWL08-1.5DN inductive proximity sensor works by generating an electromagnetic field from its sensing face.

When there is no metallic object within the sensing area, the electromagnetic field remains stable.

When a metallic target approaches the sensing surface, the target affects the electromagnetic field. The internal electronic circuit detects this change and switches the sensor output.

Because the sensor uses inductive technology, no physical contact between the sensor and the target is required.

The NPN normally open output can then send a switching signal to compatible equipment such as:

• PLC

• Counter

• Industrial controller

• Machine control circuit

• Automation system

The control system can use the signal to detect the presence or position of a metallic component.
