Why Choose the Carlo Gavazzi S142APPT924 Photoelectric Amplifier?

The Carlo Gavazzi S142APPT924 is a single-channel photoelectric sensor amplifier with PNP outputs designed for use with compatible separate through-beam photoelectric sensors. Part of the Carlo Gavazzi S142 series, it provides reliable signal processing, adjustable sensing distance and diagnostic functions for industrial automation and machine-control applications.

The S142APPT924 is designed for through-beam sensing systems with an operating range of up to 50,000 mm (50 m), depending on the connected emitter and receiver. Adjustable sensitivity and alignment assistance simplify commissioning, while integrated sensor diagnostics help identify operating conditions that could affect reliable detection.

Operating from a versatile 24 V AC/DC supply, the S142APPT924 provides PNP transistor output and PNP alarm output functionality for integration with PLCs and industrial control equipment. Its compact 35 × 80 × 81.5 mm housing and 11-pole plug connection make it a practical amplifier for control-panel and machine installations.

Reliable Long-Range 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. Interruption of the beam provides reliable object detection, making this sensing principle particularly suitable for long-range applications and industrial environments where dependable presence monitoring is required.

The Carlo Gavazzi S142APPT924 enhances this arrangement with adjustable sensing distance, alignment assistance and diagnostic signalling. Its 24 V AC/DC supply and PNP outputs enable straightforward integration with PLCs and other industrial automation equipment, while the plug-in format supports convenient installation and servicing.

Typical Applications

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