Photoelectric immaterial barriers for sectional and high-speed doors
As with all other Witt products, the LIGI 07 barrier has been specifically designed to operate in the harsh conditions typical of industrial gates.
The super-compact, integrated design measures just 12x15mm, offering perfect protection against the humidity and vibrations typical of automatic door installations.
The LIGI 07 barrier sets new standards for the future with state-of-theart electronics and intelligent firmware.
It is compatible with all standard control units for automation and can be used with almost all existing systems.
