DIFFUSED BEAM SENSORS

This device consist of a transmitter and a receiver together. This look alike Inductive Proximity Sensor and hence is also known as IR Proximity Sensor. The emitter emits Infra red rays which are reflected on the receiver through the object to be registered. In the use of these sensors, it is important to bear in mind the colour of the object. Light colour corresponds to the maximum distance and vice versa. In case of shiny object; the effect of surface of object is more important than the colour.

- Transmitter and receiver are housed in the same housing.
- As the self reflection of an object is used for detection; Dark & Light marks can be distinguished.

These Sensors are particularly used for position sensing and counting of non metallic objects. It is also used for Bottle sensing, Label sensing, Level sensing, Height sensing, Plastic film sensing, Edge detection of paper or sheet metal etc.
