Optex Bx 80Nr Picture

Product Details

BX-80N has been replaced and upgraded with award-winning curtain sensors BX Shield Series.

The BX-80N provides a curtain detection range from 2m to 12m on each side (left and right) which is ideal to protect the immediate boundary of a building. When located on a house or building facade, it will detect people getting right next to the wall or leaning towards the windows making it a perfect early intrusion detection sensor.

Animal tolerant and very stable

The BX series is very stable to use in outdoor environments with small animals around. The sensor sends infrared beams on each side, both the top and bottom of the sensor. The beams need to detect a presence to trigger, so a bird or a cat sitting on the window seal will not set the alarm off. Additionally, the BX-80 has extra features such as double conductive shielding, advanced temperature compensation and size judging function to provide reliable and stable detection.

Advanced temperature compensation

The BX-80N/80NR uses advanced temperature compensation to automatically increase the detector's sensitivity under high-temperature conditions, especially where the background temperature ranges from 35 -37 degree C, close to that of the human body.
