The system light barrier provides varied application
possibilities both indoors and outdoors.
Application-specific light curtains can be realized using
different sizes and swivel lenses.
For outdoor applications are versions with integrated
heater available (IRS-509-O).The heater prevents con-
densation on the glass pane and light barrier lens.
The infrared light barrier operates with modulated in-
frared signals.This type of transmission technology
ensures an extremely high interference immunity so that
even a false alarm signal due to sunlight is impossible.
Increased security against tamper and other infrared
external signals are achieved by signal shape monito-
ring with automatic amplification and digital threshold
Fields of application:
- Large shop windows
- Museums, exhibitions
- Fences, gates, passageways
- Shop windows, inside and outside
- Cellar windows, skylights, roof windows
- Balconies, conservatories, greenhouses
- Light shafts, air conditioning and ventilation shafts
- Escalators, staircases
- EDP rooms, monitoring of raised double floors
- Monitoring of barriers and height
- Control and monitoring of single entry access portals
- Unit surveillance, production lines
