Why Choose the Carlo Gavazzi PA12BNT20 Photoelectric Emitter?
The Carlo Gavazzi PA12BNT20 is a compact through-beam photoelectric emitter designed for long-range object and presence detection in industrial automation, door, gate and machine-safety applications. Part of the Carlo Gavazzi PA12 series, it projects a modulated infrared beam towards a compatible receiver, allowing reliable detection when an object interrupts the light path.
The PA12BNT20 provides a sensing range of up to 20 m when paired with the appropriate receiver and uses 860 nm modulated infrared light for stable through-beam operation. It operates from a 10–30 V DC supply and incorporates a low-active mute input, supporting integration into compatible safety-related door and access systems.
Built in a compact M12 cylindrical threaded metal housing, the PA12BNT20 is supplied with an integral 5 m cable and provides IP67 protection against dust and water ingress. Its ESPE Type 2 classification and compatibility with standards including EN 12445, EN 12453, EN 12978 and UL 325 make it well suited to automated access and industrial sensing applications.

Reliable Through-Beam Detection for Industrial Automation
Through-beam photoelectric systems use separate emitter and receiver units positioned opposite one another. The PA12BNT20 generates the modulated infrared beam, while the corresponding receiver monitors that beam and changes state when an object interrupts the optical path.
This sensing method provides long operating distances and dependable object detection because the receiver detects light directly from the dedicated emitter. The PA12BNT20 is therefore well suited to automated gates, industrial doors, conveyors and machinery where reliable beam interruption detection is required across relatively large distances.
Typical Applications
- Automated industrial doors and gates.
- Machine access and presence-detection systems.
- Conveyor object detection.
- Packaging and production machinery.
- Material handling systems.
- Warehouse and logistics automation.
- Long-range industrial photoelectric sensing.
- Compatible safety-related access-control systems.
