Why Choose the Carlo Gavazzi PA18ALR30TCSA Photoelectric Sensor?

The Carlo Gavazzi PA18ALR30TCSA is a robust retro-reflective photoelectric sensor designed for dependable object detection in industrial automation. Part of the Carlo Gavazzi PA18 Series, it uses a reflector to return the emitted infrared beam and provides a sensing range of up to 3000 mm.

The PA18ALR30TCSA operates from a wide 20–250 V AC supply and features a two-wire normally closed (NC) output. Its modulated 880 nm infrared light, dark-switching operation and adjustable sensitivity provide a practical sensing solution for conveyors, packaging equipment, material handling systems and general industrial machinery.

Designed for heavy-duty applications, the sensor uses a long M18 cylindrical threaded metal housing with durable nickel-plated brass construction. This cable-connected version is supplied with an integral 2 m cable, while IP67 ingress protection, LED output indication and high immunity to ambient light support reliable operation in demanding industrial environments.

Key Advantages

  • Retro-reflective sensing provides dependable object detection using a separate reflector.
  • Long sensing distance of up to 3000 mm.
  • Wide 20–250 V AC supply range for compatible industrial control systems.
  • Two-wire normally closed (NC) output simplifies installation.
  • Adjustable sensitivity allows the sensor to be optimised for the application.
  • Heavy-duty M18 nickel-plated brass housing provides robust mechanical protection.
  • Integral 2 m cable enables direct electrical connection.
  • IP67 protection supports use in dusty and wet industrial environments.

  • Carlo Gavazzi PA18 Series photoelectric sensor.
  • Retro-reflective sensing principle.
  • Maximum sensing range of 3 m.
  • 880 nm modulated infrared light.
  • 20–250 V AC operating supply.
  • Two-wire output.
  • Normally closed (NC) switching function.
  • Dark-switching sensing mode.
  • Manual sensitivity adjustment.
  • Switching frequency up to 20 Hz.
  • Integral 2 m cable.
  • M18 cylindrical threaded metal housing.
  • LED output indication.
  • IP67 ingress protection.

Reliable Retro-Reflective Detection for Industrial Automation

Retro-reflective photoelectric sensing places the emitter and receiver within the same sensor housing and uses a reflector installed on the opposite side of the detection area. An object is detected when it interrupts the returned infrared beam, allowing reliable non-contact detection while requiring electrical wiring on only one side of the application.

The Carlo Gavazzi PA18ALR30TCSA combines this proven sensing principle with a rugged M18 metal body, adjustable sensitivity, wide AC operating voltage and integral cable. Its long sensing range and IP67 construction make it a practical choice for machine builders and automation engineers requiring a durable retro-reflective sensor for general industrial applications.

Typical Applications

  • Conveyor object and product detection.
  • Packaging and processing machinery.
  • Automated assembly equipment.
  • Material handling and sorting systems.
  • Product counting and position monitoring.
  • Warehouse and logistics automation.
  • Industrial doors and access equipment.
  • General industrial automation and machine control.
