Safety Light Curtains (XUSL)
Light curtains protect an opening that has to stay open — material infeed, an operator loading position, a robot cell entrance. Resolution defines what the barrier detects: 14 mm for finger protection close to the hazard, 30 mm for hand protection at a distance calculated from the stopping time of the machine. Muting and blanking allow product to pass while a person still cannot.

Key characteristics
- Type 2 and Type 4 barriers to IEC 61496
- 14, 20 and 30 mm resolution; protected heights from 150 mm upward
- Muting, fixed and floating blanking functions
- Integrated or external muting lamp and diagnostics
- Cascadable transmitters/receivers for multi-side protection
Typical applications
Operator access openings on presses, robot cells and packaging lines
