Why Choose the Carlo Gavazzi PB18CNT15PC Photoelectric Sensor?
The Carlo Gavazzi PB18CNT15PC is a compact and reliable through-beam photoelectric receiver designed for industrial sensing, access control and automation applications. As part of the Carlo Gavazzi PB18 photoelectric sensor series, it provides dependable long-range object detection using modulated infrared light and a robust PNP normally closed switching output.
This sensor is designed to operate together with a compatible PB18 through-beam emitter, providing a sensing range of up to 15 m. Its infrared optical system uses a wavelength of 890 nm, helping deliver reliable detection where accurate beam interruption sensing is required. The receiver operates in dark-switching mode, changing its output state when the transmitted light beam is interrupted.
With a 10–30 V DC supply, PNP normally closed output and integrated 5 m cable, the PB18CNT15PC is well suited to industrial control systems, automated gates, doors and machinery. Its compact 18 mm format and IP67 protection rating support dependable installation in demanding environments.

Reliable Photoelectric Detection for Automation Systems
Through-beam photoelectric sensors use a separate emitter and receiver positioned opposite each other. The emitter transmits an infrared beam towards the receiver, and the sensor detects an object when that beam is interrupted. This operating principle provides excellent sensing reliability and allows significantly longer detection distances than many diffuse or retro-reflective sensor arrangements.
The PB18CNT15PC combines long-range optical detection with a PNP normally closed interface suitable for PLCs, control relays and industrial automation equipment. Its compact construction, sealed housing and integrated cable make it particularly useful where dependable sensing is required in machinery, doors, gates and material handling systems.

- Automatic doors and industrial gate systems.
- Conveyors and material handling equipment.
- Industrial machinery and automation systems.
- Object presence and position detection.
- Production and packaging equipment.
