Through beam sensors

A through beam sensor system consists of two separate components: the transmitter and the receiver. The transmitter sends a concentrated ray of light that impinges the receiver. An object is detected if the ray is interrupted by it. Through beam sensors from autosen are available in an ultra-compact cuboidal form with a stainless steel housing, in a compact form with a plastic housing and with M12 and M18 threads in a stainless steel cylindrical form.

Advantages and disadvantages of through beam sensors

Through beam sensors can be used where long distances are involved because the light only has to travel in one direction. Application-related disturbances such as dust in the air, soiling on the lenses, steam or fog do not immediately cause the system to malfunction. Non-transparent objects are registered reliably.

However, through beam sensors also have disadvantages: Two different devices have to be installed and adjusted. For reliable operation, the through beam sensor has to be installed very carefully.
