Why Choose the Carlo Gavazzi PA18CLD04TOSA Photoelectric Sensor?
The Carlo Gavazzi PA18CLD04TOSA is a compact and reliable diffuse-reflective photoelectric sensor designed for non-contact object detection in industrial automation, conveying and machine control applications. As part of the Carlo Gavazzi PA18 series, it combines an M18 cylindrical threaded plastic housing with straightforward two-wire AC switching.
This sensor uses infrared modulated light at 880 nm to detect light reflected directly from the target object, eliminating the need for a separate reflector or receiver. Its adjustable sensitivity allows the detection point to be configured for the application, while the normally open SCR output provides convenient integration with AC control circuits.
With a rated operating distance of 0–400 mm, a 20–250 V AC supply, an integral 2 m cable and IP67 protection, the PA18CLD04TOSA is well suited to packaging machinery, conveyors, production equipment and general factory automation.

Reliable Diffuse-Reflective Detection for Industrial Machinery
Diffuse-reflective photoelectric sensors transmit light towards a target and detect the light reflected directly back from its surface. This allows machinery to identify the presence or position of objects without mechanical contact and without the separate reflector required by retro-reflective sensing systems.
The PA18CLD04TOSA combines a useful 400 mm maximum sensing distance with adjustable sensitivity, a wide AC supply range and a robust M18 housing. Its integral cable and IP67 protection make it a practical general-purpose sensing solution for automated machinery and production equipment.
Typical Applications
- Conveyor object and package detection.
- Packaging and production machinery.
- Component presence and position detection.
- Material handling systems.
- Product counting applications.
