Reliable Through-Beam Detection for Industrial Automation
Through-beam photoelectric sensing uses separate transmitter and receiver units positioned opposite one another. The receiver continuously monitors the infrared beam from the transmitter, enabling the control system to detect when an object or obstruction changes the beam condition. This principle provides dependable detection over considerably longer distances than many single-housing photoelectric sensing methods.
The Carlo Gavazzi PA12 Series combines through-beam sensing with a compact cylindrical format suited to machinery and powered access equipment. The PA12B2T20NO receiver's NPN normally open output, 10–30 V DC supply range, 20 m sensing capability, integral cable and IP67 construction support straightforward integration into industrial detection and control systems.
Typical Applications
- Powered industrial doors and automated gates.
- Machine access and obstruction detection systems.
- Conveyors and material handling equipment.
- Packaging and production machinery.
- Object detection across extended distances.
- Warehouse and logistics automation.
- Industrial automation and control systems.
