A. Product Overview

The Autonics PRD30-25DP is a cylindrical inductive proximity sensor designed for applications requiring a longer sensing distance than conventional inductive sensors.

With an M30 sensing head diameter and 25 mm sensing distance, the PRD30-25DP can detect metallic objects without requiring physical contact with the target.

The sensor uses a non-flush mounting arrangement and provides a PNP output suitable for compatible PLCs, controllers and industrial automation systems.

Its rugged construction, protection circuits and IP67 enclosure make it suitable for demanding industrial environments.

B. Working Principle

The Autonics PRD30-25DP inductive proximity sensor detects metallic objects using an electromagnetic sensing field.

The sensor generates an electromagnetic field from its sensing surface.

When no metallic object is present, this field remains in its normal condition.

When a metal target enters the sensing area, the electromagnetic field changes. The internal electronic circuit detects this change and switches the sensor output.

The PNP output signal can then be used by a compatible:

• PLC

• Industrial controller

• Counter

• Machine control circuit

• Automation system

Because detection is performed without physical contact, the sensor can repeatedly detect moving metal components without the mechanical wear associated with conventional limit switches.

C. Why Is the Autonics PRD30-25DP Used?

The PRD30-25DP is particularly useful when a machine requires reliable metal detection from a relatively long sensing distance.

1. Long Distance Metal Detection

The 25 mm sensing distance provides greater detection range than many conventional M30 proximity sensors.

2. Machine Position Detection

The sensor can detect whether a metallic machine component has reached a required position.

3. Conveyor Object Detection

It can detect metallic products, fixtures or components moving along conveyor systems.

4. Production Counting

The sensor output can be connected to a PLC or counter for counting metallic parts passing through a production process.

5. Automation Sequence Control

Detection of a metal target can be used as a condition for starting the next stage of an automated process.

6. Limit Position Detection

The sensor can be used to confirm the end position of suitable metallic machine components.

7. Non-Contact Detection

There is no need for the target to physically press or touch the sensor.

8. Reduced Mechanical Wear

Unlike mechanical limit switches, inductive sensing does not rely on repeated physical contact.

9. Industrial Environment Protection

The IP67 protection rating makes the sensor suitable for industrial environments where dust and moisture may be present.

10. PLC Integration

The PNP output allows the sensor to be integrated with compatible PLC digital input systems.
