Photo Electric Switches are used for Motion Control Automation in conveying unit goods like Boxes, Cartoons, Bottles, and Containers etc. Levels of Bulk Materials are often sensed by such switches. Various types of logics for Automatic Operations, Actuation of Alarms etc are carried out by using the Photo Electric Switches in the Control Circuit of the Electrical Panel. These are usually field mounted on suitable support clamps.



Easy-to-use, low-cost Photoelectric Sensor: M18 DIN-sized cylindrical housing.

Housing materials: plastic, nickel-brass, and stainless steel. Through-beam, Retro-Reflective and Diffuse models. DC switching type with connectors for easy maintenance. Wide operating Voltage Range (10 to 30 V (DC) or 24 to 240 V (AC)). Short-circuit and reverse connection protection (DC switching type). Both AC and DC models available.




Application Examples:


Detecting the presence of an opaque bottle on a conveyor line.





Detecting the presence of cardboard boxes on a packaging line.





Detecting the presence of drinks cartons on a filling line.
