Why Choose the Carlo Gavazzi PH18CNT20NAM1SA Through-Beam Photoelectric Sensor?
The Carlo Gavazzi PH18CNT20NAM1SA is a compact through-beam photoelectric receiver designed for reliable object detection in industrial automation and machine control applications. As part of the Carlo Gavazzi PH18 photoelectric sensor series, it combines a space-saving square/M18-style housing with a long sensing distance of up to 20 m when paired and correctly aligned with the corresponding through-beam emitter.
Through-beam sensing uses separate emitter and receiver units positioned opposite one another, providing dependable detection when an object interrupts the optical path. The PH18CNT20NAM1SA provides NPN complementary NO+NC outputs, giving both normally open and normally closed switching signals for flexible integration with PLCs, controllers and industrial machinery.
Operating from a 10–30 V DC supply, the PH18CNT20NAM1SA features an M12 plug connection for convenient installation, servicing and replacement. Its compact and robust housing is designed for demanding industrial environments, making the sensor suitable for conveyors, packaging equipment, material handling systems and automated production machinery requiring reliable long-range detection.

Reliable Long-Range Through-Beam Detection
Through-beam photoelectric sensing uses a separate transmitter and receiver positioned opposite one another. The transmitter directs a modulated light beam towards the receiver, and an object is detected when it passes between the two devices and interrupts the beam. Because detection does not depend on light being reflected directly from the target, through-beam technology is particularly effective for reliable long-distance sensing.
The Carlo Gavazzi PH18 series combines this dependable sensing principle with compact construction suitable for modern industrial machinery. The PH18CNT20NAM1SA provides a 20 m sensing capability, complementary NPN switching and an M12 plug connection, making it a practical choice for machine builders and automation engineers requiring reliable detection with straightforward installation and maintenance.
