Why Choose the Carlo Gavazzi S142ARNN230 Photoelectric Sensor Amplifier?

The Carlo Gavazzi S142ARNN230 is a reliable single-channel photoelectric sensor amplifier designed for use with separate through-beam photoelectric sensors in industrial automation and machine-control applications. As part of the Carlo Gavazzi S142A series, it combines adjustable sensing distance, sensor diagnostics and alignment assistance to support dependable object detection and straightforward commissioning.

This amplifier supports through-beam sensing systems with an operating distance of up to 50,000 mm. Automatic or manual emitter power regulation allows the sensing system to be optimised for the application, while integrated diagnostic functions provide useful status information for setup, operation and maintenance.

With a nominal 230 V AC supply, the S142ARNN230 provides an SPDT change-over relay output plus NPN transistor output and NPN alarm functionality. Its compact plug-in housing and 11-pole connection make it particularly suitable for installation in industrial control panels and automation systems.

Reliable Photoelectric Detection for Industrial Automation

Photoelectric amplifier systems such as the Carlo Gavazzi S142ARNN230 process signals from separate through-beam emitter and receiver sensors and convert the detection status into switching signals for industrial control equipment. The separate amplifier architecture is particularly useful where sensing heads need to remain compact while adjustment and diagnostics are located conveniently within the control system.

The S142A series provides adjustable sensing distance, emitter power regulation, alignment assistance and self-diagnostic functions to help achieve stable detection. Its combination of relay and transistor outputs provides flexible integration with PLCs, relays and other industrial automation equipment.

Typical Applications

  • Industrial through-beam photoelectric sensing systems.
  • Conveyor and material handling equipment.
  • Packaging and production machinery.
  • Object, presence and position detection.
  • Automated assembly and manufacturing equipment.
  • Machine control and industrial automation systems.
