Why Choose the Carlo Gavazzi PB10CNT20PO Through-Beam Photoelectric Receiver?
The Carlo Gavazzi PB10CNT20PO is a compact through-beam photoelectric receiver designed for reliable object, presence and obstruction detection in industrial automation and entrance-control systems. As part of the Carlo Gavazzi PB10 series, it combines a slim cylindrical housing with a PNP normally open transistor output for straightforward integration with PLCs and machine-control equipment.
Designed to operate with a separate compatible through-beam emitter, the PB10CNT20PO provides a sensing range of up to 20 m. Its light-switching operation and infrared sensing system provide dependable detection across extended distances, while adjustable sensitivity helps optimise the sensor for the installation.
The PB10CNT20PO operates from a 10–30 V DC supply and provides a PNP normally open (NO) output rated up to 100 mA. Its compact Ø10 mm plastic housing, integral 5 m cable and IP67 protection make it particularly suitable for elevators, escalators, powered doors, gates and industrial machinery.

Reliable Long-Range Through-Beam Detection
Through-beam photoelectric sensing uses separate emitter and receiver units positioned opposite one another. The PB10CNT20PO monitors the infrared beam generated by the compatible emitter and provides a PNP normally open switching signal for use by PLCs, safety-related control equipment and other industrial automation systems.
The combination of a 20 m sensing range, compact Ø10 mm housing and adjustable sensitivity makes the PB10CNT20PO especially useful for powered entrances and machinery where reliable detection is required over significant distances. Reverse-polarity, short-circuit and transient protection further support dependable industrial operation.
