Photobeams - Optex Beams
Optex AX200TF

The AX-200TF long range photoelectric detector with selectable beam frequency has a built in setting to avoid cross-talking when multiple photobeams are online and will almost never send you a false alarm due to birds or other small animals near the device!

The AX-200TF long range photoelectric detectors with selectable beam frequencies can be used to sidestep cross-talk that occurs when using more than one photobeams over really long distances or from using other beam stacking applications.

On top of that, the AX-TF Series employs multiple beam technology and utilizes an AMD circuit that requires all beams to be interrupted simultaneously before an alarm is generated. With this technology implemented, the chances of a false alarm being called from tiny animals (eg. birds) is very minimal.
