Why Choose the Carlo Gavazzi PH18CNT20NAT1SA Photoelectric Sensor?
The Carlo Gavazzi PH18CNT20NAT1SA is a compact through-beam photoelectric receiver designed for reliable long-range object detection in industrial machinery and automation systems. As part of the Carlo Gavazzi PH18 photoelectric sensor series, it combines a space-saving square/M18 special housing with a powerful optical system for applications requiring accurate detection over extended distances.
The PH18CNT20NAT1SA operates as the receiver in a separate transmitter-and-receiver photoelectric system, providing a sensing range of up to 20 m. It detects 850 nm modulated infrared light and provides NPN complementary NO+NC outputs, allowing both normally open and normally closed switching functions for flexible PLC and machine-control integration.
With a 10–30 V DC supply, switching frequency up to 500 Hz and a convenient M12 pigtail connection, the PH18CNT20NAT1SA is well suited to modern automated equipment. Its compact plastic housing provides IP67 / IP69K protection and ECOLAB suitability, making the sensor suitable for demanding production and washdown environments.

Reliable Long-Range Through-Beam Detection for Industrial Automation
Through-beam photoelectric systems use a separate transmitter and receiver positioned opposite one another. The transmitter directs a modulated infrared beam towards the receiver, and an object interrupting that beam causes the receiver output to change state. This configuration provides excellent sensing reliability and long operating distances for industrial presence, position and counting applications.
The Carlo Gavazzi PH18 series combines through-beam sensing performance with compact square/M18 construction. The PH18CNT20NAT1SA provides complementary NPN outputs, fast switching, an M12 pigtail connection and high environmental protection, making it a versatile receiver for conveyors, packaging systems, material handling equipment and automated production machinery.
Typical Applications
- Long-range conveyor object detection.
- Packaging and bottling machinery.
- Part presence and position monitoring.
- High-speed product counting.
- Automated material handling systems.
- Food and beverage production equipment.
- OEM machinery and industrial automation systems.
