LIGI-OSE safety light curtain


Maximum operational reliability
The mechanical construction of the LIGI, a aluminium profile fully filled with epoxy resin and high-grade connector, is extremely robust in line with the tough environmental demands imposed on gate systems. The LIGI is highly insensitive against ambient light, even direct sunlight does not impair its functionality. The LIGI is also resistant to electromagnetic interference such as can occur in door drives that use low-frequency inverters.

A high rate of variant diversity
The rate of product variants is very high. Various combinations of protection field height, beam geometry, semiconductor output variants or the OSE output are available for direct connection to the closing-edge inputs of most door controllers.

Retrofitting older gate systems / Compliance with ASR A 1.7
The safety light curtain is ideal for upgrading or retrofitting door systems which cannot comply with the specified maximum closing forces.

Features of the LIGI light curtain

  • Can be installed directly in the door opening instead of plane of door movement
  • Easy to service thanks to status and diagnostic indicators
  • Door widths up to 10m are easily implemented
  • Direct connection to almost all door controllers
  • High rate of variants, including for low door systems
  • High degree of protection IP67, fully filled with epoxy resin
  • Small housing dimensions of just 16x16mm
