The LIGI-01 PNP-A -41 is an intelligent light strip with a PNP output and detection height of 1,845 mm for securing a passage at a door, making the use of an edge safety device unnecessary. The LIGI-01 PNP-A -41 is suitable for mounting in the course of a door or in front of a door. When mounted in the path of a door, the light strip recognizes the door by breaking the light beams one by one from top to bottom; two light beams must always be interrupted. When another beam of light is interrupted, the door stops and opens immediately. With its minimum dimensions of only 16 x 16 mm, the LIGI can be installed in virtually any situation and the compact design allows a monitoring field almost up to the lintel. The epoxy resin-filled aluminum housing ensures high IP protection and is also environmentally friendly.
