Why Choose the Carlo Gavazzi S142BRNN115 Photoelectric Amplifier?

The Carlo Gavazzi S142BRNN115 is a single-channel photoelectric sensor amplifier designed for use with compatible separate through-beam photoelectric sensors in industrial automation and machine-control applications. Part of the Carlo Gavazzi S142 series, it combines an SPDT changeover relay with NPN transistor output functionality, adjustable sensitivity, diagnostics and an integrated time-delay function.

The S142BRNN115 supports through-beam sensing systems with a rated operating distance of up to 50,000 mm (50 m), depending on the compatible emitter and receiver arrangement. Adjustable sensitivity and alignment assistance simplify commissioning, while selectable light-on and dark-on switching enables the sensing response to be configured for different detection requirements.

Operating from a 115 V AC supply, the S142BRNN115 provides an SPDT relay plus NPN output, together with an alarm output and time-delay functionality. Its rectangular plastic housing, IP20 protection and 11-pole plug-in connection make it a practical solution for industrial control installations requiring dependable long-range photoelectric detection.

Reliable Timed Photoelectric Detection for Industrial Automation

Separate-amplifier through-beam photoelectric systems use an emitter and receiver positioned opposite one another, with the amplifier processing the received optical signal. When an object interrupts the beam, the amplifier changes its output state, providing reliable presence detection over long distances in machinery and automated production systems.

The Carlo Gavazzi S142BRNN115 adds adjustable sensitivity, alignment assistance, diagnostics, alarm signalling and time-delay functionality to this sensing arrangement. Its combination of SPDT relay and NPN outputs provides flexible integration with industrial control equipment, while the 115 V AC supply makes it suitable for control systems using this established industrial voltage.

Typical Applications

  • Conveyor product and object detection.
  • Packaging and production machinery.
  • Long-range through-beam sensing systems.
  • Material handling and logistics equipment.
  • Timed presence and position detection.
  • Industrial doors and access-control equipment.
  • Manufacturing and assembly machinery.
  • OEM automation and machine-building systems.
