Optex 200m PE Beam, Quad Beam, Double Modulation, 4 x Selectable Frequencies, IP65, 10.5-30VDC

The SL-650QDP is a 200m outdoor active infrared (AIR) beam set, wired designed for perimeter security. The Quad beam set features four selectable channels making it easy to stack in beam towers and dual modulation to provide a highly reliable signal transmission even when exposed to strong sunlight or light sources. The SL-650QDM can also be connected to an IP network when used in conjunction with the IP/POE module PIE-1. For installation into beam towers, we provide the SL-650QDP-BT model which doesn't include the front cover, item which is unnecessary inside the tower.
