Garrison infrared beam sensors detect interruptions or changes in an infrared sensing path. The range includes two-beam, four-beam, strip, reflector and compact designs, giving installers different ways to monitor entrances, gates and boundary lines. Choose the sensing arrangement before comparing distance ratings.
Separate transmitter and receiver arrangements need an unobstructed path and suitable alignment positions. Reflector designs use a different layout. The LK-3HR reflex-beam sensor requires no reflector and offers adjustable detection distance; its listed applications include entrances, garages and touchless device activation.
Compare the selected model’s indoor or outdoor rating, supply voltage, output interface and mounting requirements. Outdoor range and enclosure protection are model-specific, not shared specifications for every infrared beam detector. Account for sunlight, obstructions and access for alignment.
Send Garrison the opening width, detection purpose, mounting locations and connected controller details. Include expected quantities and destination market for a focused product inquiry.
