Reliable Long-Range Through-Beam Detection
Through-beam photoelectric sensing uses separate transmitter and receiver units positioned opposite one another. The transmitter projects an infrared beam towards the receiver, and an object is detected when it interrupts that beam. This arrangement provides excellent sensing distance and reliable object detection because the receiver monitors a dedicated light source rather than light reflected directly from the target.
The Carlo Gavazzi PA18CAT20M1 combines this proven sensing principle with a compact M18 format and a long 20 m operating distance. Its DC supply, modulated infrared technology and detachable M12 connection make it well suited to machine builders and automation engineers requiring dependable long-range optical detection with straightforward installation.
Typical Applications
- Long-range conveyor object detection.
- Packaging and processing machinery.
- Automated assembly and production equipment.
- Material handling and sorting systems.
- Product counting and position monitoring.
- Warehouse and logistics automation.
- Industrial doors and access equipment.
- General industrial automation requiring through-beam sensing.
