Why Choose the Carlo Gavazzi PH18CNT20PAM1SA Photoelectric Sensor?
The Carlo Gavazzi PH18CNT20PAM1SA is a compact through-beam photoelectric receiver designed for accurate long-range object detection in industrial machinery and automation systems. Part of the Carlo Gavazzi PH18 series, it combines a miniature square housing with a powerful optical system for applications where both high detection accuracy and limited installation space are important.
The PH18CNT20PAM1SA operates as the receiver in a separate transmitter-and-receiver photoelectric system and provides a rated operating distance of 20 m. It detects 850 nm modulated infrared light and provides PNP complementary NO+NC outputs, allowing normally open and normally closed switching functions for flexible integration with PLCs and machine controllers.
With a 10–30 V DC supply, sensitivity adjustment and a convenient 4-pin M12 connector, the PH18CNT20PAM1SA is engineered for straightforward machine installation and servicing. Its ABS housing provides IP67 / IP69K protection, while reverse-polarity, short-circuit and transient protection help provide dependable operation in demanding industrial environments.

Reliable Long-Range Through-Beam Detection for Industrial Automation
Through-beam photoelectric sensing uses separate transmitter and receiver units installed opposite one another. The transmitter directs a modulated infrared beam towards the receiver, and when an object interrupts that beam the receiver changes its output state. This arrangement offers excellent sensing reliability and enables significantly longer detection distances than many single-housing photoelectric sensing methods.
The Carlo Gavazzi PH18 series combines this reliable sensing principle with compact industrial-standard construction. The PH18CNT20PAM1SA adds complementary PNP outputs, sensitivity adjustment, fast switching and an M12 connector, making it a versatile receiver for conveyors, packaging systems, production machinery and automated material handling equipment.
Typical Applications
- Long-range conveyor object detection.
- Packaging and bottling machinery.
- Product counting on automated production lines.
- Part presence and position monitoring.
- Automated material handling systems.
- Food and beverage processing equipment.
- OEM machinery and industrial automation systems.
