Why cross matrix matters
Outdated conventional light curtains have linear arrays that have spaces between the beams - which can easily allow foreign objects through. Red 4, Infrascan and Flex SL each have laboratory-proven cross matrix arrays that use multiple directional beams to intermesh, reducing the possibility of object penetration. They are considerably more reliable.
Cross matrix technology also virtually eliminates alignment problems. Depending on scan distance, our guards can be off alignment by as much as 30 degrees or more and still function correctly.
Our product line
Red 4
State of the art cross matrix light curtain. Our most popular model thanks to its strong design, virtual plug-and-play installation, no-fuss alignment, and built-in safety, switching and muting electronics - no extra control modules or relays needed.
Red 4 detailsInfrascan
Cross matrix technology miniaturized. The Infrascan packs the same power as the Red 4 into a miniature device less than an inch across - the perfect finger and hand guard.
Infrascan detailsFlex SL
Our next-generation light curtain. Cross matrix tech reimagined as a cascading, multi-directional safety guard - configurable at angles to shield vital and dangerous systems more easily than conventional light curtains.
Flex SL detailsBuilt for high-risk machinery
All SafetyTec light curtains are type 4 safety as defined by EN 61496-1, and Category SIL3 PLe as defined by ISO 13849-1. They are suitable for machinery with all risk categories - including high-risk applications such as robotic cells, power presses and other dangerous machinery where safety integrity is crucial and legally required.
- No interface control boxes required - all electronics are contained within the transmitter (TX) and receiver (RX) heads.
- Standard plug-fit connectors - guards arrive ready for termination to the machine.
- Built-in switching and muting - no extra relays or modules to specify or wire.
- Tolerant of misalignment - the cross matrix array keeps working through significant alignment error.
