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.
