Why Choose the Carlo Gavazzi PA12B3T20NO Photoelectric Sensor?
The Carlo Gavazzi PA12B3T20NO is a compact through-beam photoelectric receiver designed for dependable presence and obstruction detection in industrial automation, powered doors and gate systems. Part of the Carlo Gavazzi PA12 Series, this Channel 3 receiver works with the corresponding PA12 through-beam transmitter to provide reliable non-contact detection.
The PA12B3T20NO provides an NPN normally open (NO) transistor output for straightforward integration with compatible PLCs, controllers and automation equipment. Its dedicated Channel 3 coding helps distinguish the optical transmission channel when used as part of a correctly matched PA12 transmitter and receiver installation.
A compact M12 cylindrical threaded housing makes the PA12B3T20NO suitable for installations where space is restricted, while its integral cable enables direct machine wiring. The robust construction and IP67 ingress protection support dependable operation in demanding industrial environments where dust, moisture and routine exposure to machinery conditions are expected.

Reliable Through-Beam Detection for Industrial Automation
Through-beam photoelectric sensing uses separate transmitter and receiver devices mounted opposite one another. The receiver monitors the optical beam generated by the matching transmitter, allowing a control system to detect when an object interrupts the beam. This operating principle is widely used where reliable non-contact detection across an open space is required.
The Carlo Gavazzi PA12 Series combines through-beam sensing with a compact threaded cylindrical design suited to industrial machinery and powered access equipment. The PA12B3T20NO's Channel 3 configuration and NPN normally open output make it suitable for compatible control architectures requiring a compact cable-connected receiver.
