The sensing range is fixed and defined as the focus point.
Through beam sensor working principle.
Light emitted from the transmitter is aimed directly at the receiver.
The slit on the outside of a through beam sensor that is used to detect small objects is an example of how this principle is applied to practical use.
When light travels through air or water it always travels in a straight line.
Conceptual through beam system to detect unauthorized access to a secure door.
If the beam is interrupted the detector triggers an alarm.
Through beam sensors through beam sensors also work reliably in rough environmental conditions such as steam fog or dust thanks to the increased light intensity.

Thru beam sensors in through beam photoelectric sensing or opposed mode the transmitter and emitter are in separate housings.
The transmitter can be deactivated using a separate test input in order to test the functionality of the through beam sensor.
When an object breaks the beam of light between the emitter and receiver the receiver s output changes state.
