Fork Light-Barriers
The fork-light-barriers from Xecro work on the principle of the one way light barrier. The electronic circuitry and the optical elements which are protected by scratch resistant mineral glass are built into a very robust metal casing. Time consuming calibration and complicated fitting is not necessary. Even the smallest parts traveling at high speeds can be detected thanks to the ambient light immunity, switch speed and resolution. The use of class 2 collimated laser improves the resolution compared to red light versions even more. The laser collimator emits a very small but clearly visible dot and so a very exact aim can be taken on the switch point.
