Safety light curtains

Small design, great flexibility, and universal possibilities

Your Benefits

  • Cost-effective machine integration: the miniature design, cascading, and fine stepping of the protective field lengths enable flexible adaptation to the machine design
  • Standardization saves time and resources by making logistics, order processing, and service more straightforward
  • Exemplary handling: software-free, almost fully automatic commissioning and intuitive operation with sustainable optics
  • LED-guided start-up together with colored LEDs for quick alignment and unequivocal protective field visualization ensure rapid diagnostics
  • A continuous protective field for cascade applications eliminates blind zones, reduces the safety distance, and thereby increases productivity
  • Application-specific brackets increase mounting flexibility, while reducing the mounting time


Small design, great flexibility, and universal possibilities

The miniTwin2 safety light curtain is currently the smallest electro-sensitive protective device of its kind. It is mainly used at hazardous points for finger and hand protection. The sender and receiver are combined and integrated into an extremely compact housing. Whether it is used as a standalone device or it is cascaded with other miniTwin light curtains, the miniTwin2 enables machine access protection up to the safety level PL c. Protective field heights ranging from 120 mm to 1,200 mm are available and it is possible to cascade up to three systems. Individual protective fields are extremely easy to implement by virtue of housing lengths in 60-mm increments. Commissioning, which is almost completely automatic, requires no software. This along with the bracket sets saves valuable installation time. The miniTwin2 offers a first-rate, modern, industrial design that combines an intuitive operating system with sustainable optics.
