Why Choose the Carlo Gavazzi PH18CNT20T1 Through-Beam Photoelectric Emitter?
The Carlo Gavazzi PH18CNT20T1 is a compact through-beam photoelectric emitter designed for reliable long-range optical sensing in industrial automation and machine-control applications. As part of the Carlo Gavazzi PH18 photoelectric sensor series, it combines square housing construction with M18-style optics and is designed to operate with a compatible PH18 through-beam receiver.
The PH18CNT20T1 transmits 850 nm modulated infrared light towards the corresponding receiver, creating a through-beam sensing system with a rated operating distance of up to 20 m. This separate emitter-and-receiver arrangement provides dependable object detection across conveyors, machine openings and material-handling systems.
Operating from a 10–30 V DC supply, the PH18CNT20T1 features a pigtail M12 connection for convenient installation and servicing. Its robust plastic housing provides IP67 / IP69K protection, while UL 508 recognition and ECOLAB suitability support use in demanding industrial and washdown environments.

Reliable Long-Range Through-Beam Detection
Through-beam photoelectric sensing uses a separate emitter and receiver installed on opposite sides of the detection area. The PH18CNT20T1 transmits a modulated infrared beam towards its compatible receiver, allowing objects to be detected when they interrupt the optical path between the two devices.
This sensing principle offers reliable long-distance detection and is well suited to conveyors, packaging equipment and automated machinery. The PH18CNT20T1 combines a 20 m operating range with compact construction, M12 connectivity and high ingress protection, making it suitable for both conventional industrial environments and applications involving intensive cleaning.
Typical Applications
- Conveyor and material-handling systems.
- Packaging and processing machinery.
- Long-range object and package detection.
- Production and assembly equipment.
- Food and beverage processing machinery.
- Washdown production environments.
- Industrial automation and machine-control systems.
