pb12rnpa – photo tr pl npn no+nc cab
Carlo Gavazzi PB12RNPA is a cable-connected through-beam photoelectric receiver with an adjustable 12 m sensing distance, 10–30 V DC supply and complementary NPN NO+NC outputs for industrial automation.
Why Choose the Carlo Gavazzi PB12RNPA Photoelectric Sensor?
The Carlo Gavazzi PB12RNPA is a robust through-beam photoelectric receiver designed for reliable long-range object detection in industrial automation and machine-control applications. Part of the Carlo Gavazzi PB flat-housing photoelectric sensor family, it provides an NPN complementary NO+NC output for flexible integration with PLCs, relays and industrial control circuits.
Designed to operate with a compatible PB12 through-beam transmitter, the PB12RNPA offers an adjustable sensing distance of up to 12 m. Through-beam technology positions the transmitter and receiver opposite one another, providing dependable detection when an object interrupts the optical path and making the sensor particularly suitable for applications requiring reliable sensing over greater distances.
The PB12RNPA operates from a 10–30 V DC supply and supports load currents up to 200 mA. Its reinforced ABS flat housing, IP67 protection rating and pre-wired 2 m cable provide a practical combination of durability and straightforward installation for industrial equipment.

Reliable Long-Range Photoelectric Detection
Through-beam photoelectric systems use separate transmitter and receiver units installed opposite each other. The receiver continuously monitors the transmitted beam, allowing an object to be detected when it passes between the two devices and interrupts the optical path. This arrangement provides reliable sensing over substantially greater distances than many diffuse-reflective sensing methods.
The PB12RNPA combines an adjustable 12 m sensing distance with complementary NPN outputs and a high operating frequency, making it suitable for both general presence detection and faster industrial processes. Its protected reinforced ABS housing and cable connection support dependable installation in production machinery, conveyors and material-handling systems.
Typical Applications
- Conveyor and material handling systems.
- Packaging and production machinery.
- Object and presence detection.
- Industrial doors and access systems.
- Warehouse and logistics automation.
- Counting and position-detection applications.
- PLC-controlled industrial machinery.
