Reliable Through-Beam Detection for Industrial Automation
Through-beam photoelectric sensing uses separate transmitter and receiver units installed opposite one another. The receiver monitors the infrared beam produced by the matching transmitter, allowing an object or obstruction to be detected when the beam condition changes. This arrangement provides reliable non-contact detection across comparatively long distances.
The Carlo Gavazzi PA12 Series combines through-beam sensing with a compact M12 cylindrical format suited to machinery, powered doors and access equipment. The PA12B3T20PC's PNP normally closed output, Code 3 optical configuration, wide DC supply range and robust IP67 construction support straightforward integration into industrial automation and detection systems.
Typical Applications
- Powered industrial doors and automated gates.
- Machine access and obstruction detection systems.
- Conveyors and material handling equipment.
- Packaging and production machinery.
- Presence and object detection across extended distances.
- Warehouse and logistics automation.
- Industrial automation and control systems.
