Why Choose the Carlo Gavazzi PMT20RG Through-Beam Photoelectric Sensor?

The Carlo Gavazzi PMT20RG is a robust through-beam photoelectric sensor designed for reliable long-distance object detection in industrial automation, machinery and material handling applications. Part of the Carlo Gavazzi PMT photoelectric sensor series, it provides dependable sensing performance using separate emitter and receiver units for accurate beam interruption detection.

The PMT20RG uses a through-beam sensing principle with a 20 m operating distance, making it suitable for applications where reliable detection across larger areas is required. The separate optical path between emitter and receiver provides excellent immunity to target colour, shape and surface characteristics compared with diffuse sensing technologies.

Featuring an SPDT relay output with normally open and normally closed contacts, the PMT20RG provides flexible connection to industrial control circuits. Its rugged construction, threaded mounting format and long sensing range make it suitable for conveyors, production machinery, access systems and industrial automation equipment.

Key Advantages

  • Reliable through-beam photoelectric detection for industrial applications.
  • 20 m sensing distance supports long-range object monitoring.
  • Separate emitter and receiver configuration improves detection reliability.
  • Less affected by target colour, texture and surface reflectivity.
  • SPDT relay output provides both NO and NC switching contacts.
  • Suitable for machine control, conveyors and industrial automation systems.
  • Robust housing designed for demanding operating environments.

Key Features

  • Carlo Gavazzi PMT photoelectric sensor series.
  • Through-beam detection principle.
  • 20 m rated operating distance.
  • SPDT relay output.
  • Normally open and normally closed changeover contacts.
  • Separate emitter and receiver arrangement.
  • Suitable for long-distance industrial object detection.
  • Designed for integration into automation and control systems.

Reliable Through-Beam Detection for Industrial Automation

Through-beam photoelectric sensors use separate transmitter and receiver units positioned opposite one another. The emitter sends a continuous optical beam towards the receiver, and an object is detected when it interrupts this beam. This technology provides reliable sensing over long distances and is particularly effective where target appearance or reflectivity may vary.

The Carlo Gavazzi PMT20RG combines long-range optical detection with a flexible relay output, allowing simple integration into a wide range of industrial control applications. Its dependable sensing principle makes it suitable for automated machinery, conveyors and production systems requiring consistent object detection.

Typical Applications

  • Industrial automation machinery.
  • Conveyor and material handling systems.
  • Packaging and production equipment.
  • Machine access and presence detection.
  • Automated assembly systems.
  • Warehouse and logistics automation.
  • OEM machinery and industrial control systems.
