Optex 20m Twin Beam
The AX-70TN is a 20m indoor and outdoor hardwired active infrared (AIR) beam set, designed to protect driveways, loading bays in warehouses, open areas and small perimeters. The dual beam set can also be connected to an IP network when used in conjunction with the IP/POE module PIE-1.
The shortest and most compact of our active infrared beams, the AX-70TN is very popular for warehouse and distribution centres to detect if a loading bay is being used or empty and activate the shutter accordingly.
IP65 rated, the AX-70TN housing has been designed to resist against both water and dust. The hood featured on the front cover is to prevent frost from attaching to the cover and potentially affecting the signal power. The beam is also fitted with specific relay and absorber to protect it from lightening surges.
