Why Choose the Carlo Gavazzi S142ARNT230 Photoelectric Amplifier?

The Carlo Gavazzi S142ARNT230 is a versatile single-channel photoelectric sensor amplifier designed for reliable object detection in industrial automation, machinery and material handling systems. As part of the Carlo Gavazzi S142 series, it is designed for use with compatible through-beam photoelectric sensor heads and provides a sensing range of up to 50 m.

The S142ARNT230 combines adjustable sensitivity with diagnostic functions and alignment assistance, helping installers configure and maintain dependable photoelectric detection systems. Its selectable light-on and dark-on operation provides additional flexibility when integrating the amplifier into different machine control applications.

Operating from a nominal 230 V AC supply with an operating range of 195–265 V AC, the amplifier provides both an SPDT relay contact and NPN transistor output. An 11-pole plug-in connection simplifies installation and replacement, while its compact rectangular housing is well suited to industrial control cabinets.

Key Advantages

  • Industrial single-channel photoelectric amplifier for through-beam sensors.
  • Supports sensing distances of up to 50 m with compatible sensor heads.

Reliable Through-Beam Detection for Industrial Automation

Through-beam photoelectric systems use separate emitter and receiver sensor heads positioned opposite each other. An object is detected when it interrupts the transmitted light beam, providing reliable non-contact detection over considerably longer distances than many conventional diffuse-reflection sensing arrangements.

The S142ARNT230 provides the amplification, adjustment and output switching functions required by compatible Carlo Gavazzi through-beam sensor heads. Its long sensing range, adjustable sensitivity, diagnostic functionality and combined relay and NPN outputs make it suitable for integration into both traditional relay-controlled equipment and electronic industrial control systems.

Typical Applications

  • Industrial conveyors and material handling systems.
  • Long-distance through-beam object detection.
  • Packaging and production machinery.
  • Product presence and position monitoring.
  • Automated doors, gates and access systems.
  • Industrial assembly and processing equipment.
  • Warehouse and logistics automation.
  • OEM machinery and industrial control systems.
