Why Choose the Carlo Gavazzi PA18CAT20NAM1SA Photoelectric Sensor?
The Carlo Gavazzi PA18CAT20NAM1SA is an axial through-beam photoelectric receiver designed for reliable long-range object detection in industrial automation. Part of the Carlo Gavazzi PA18 Series, it operates with a corresponding through-beam emitter to create a dedicated optical path, providing a sensing distance of up to 20 m.
Operating from a standard 10–30 V DC supply, the PA18CAT20NAM1SA provides NPN complementary NO + NC outputs, giving both light and dark switching functionality for flexible integration with PLCs and machine-control systems. Through-beam technology is particularly effective where dependable detection over long distances is required, as the target is detected by interrupting the optical beam between the emitter and receiver.
The PA18CAT20NAM1SA uses a compact M18 cylindrical threaded plastic housing and an M12 plug connection for straightforward installation and replacement. Its rugged construction and high ingress protection make it suitable for conveyors, packaging equipment, automated production lines and other demanding industrial sensing applications.

Reliable Long-Range Through-Beam Detection
Through-beam photoelectric systems use separate transmitter and receiver units installed opposite one another. The transmitter directs a light beam towards the PA18CAT20NAM1SA receiver, and an object is detected when it interrupts that optical path. Because detection does not depend on light being reflected directly from the target, through-beam systems offer excellent sensing reliability across long distances and with objects of varying colours and surface finishes.
The Carlo Gavazzi PA18CAT20NAM1SA combines this sensing principle with complementary NPN outputs, a compact M18 housing and detachable M12 connectivity. It is an effective choice for machine builders and automation engineers requiring long-range presence detection with straightforward electrical integration and convenient sensor replacement.
