State of the art cross matrix
The Red 4 uses our famous and patented cross matrix array technology to create a matrix of infrared beams that crosses between transmitter and receiver units. This is a quantum leap forward in light curtain technology and completely eliminates the usual problems caused by alignment difficulties found in standard guards.
The Red 4 is our most popular model thanks to its strong design, virtual plug-and-play ease of installation, no-fuss alignment, and built-in safety, switching and muting electronics - removing the need for any additional control modules or relays. This also aids in speedy installs and lower costs.
How it works
"Cross matrix" is a unique patented technology where each individual infrared transmitter beam within the TX column transmits IR beams to every receiver within the RX column. This creates a cross matrix array within the safety-guarded area.
This technology serves to create better detection capability and completely eliminates any alignment problems seen in conventional light curtain types. In conventional technology guards, the transmitter column must focus each transmitted beam using optical lenses so that the beams accurately align with their corresponding receiver. If the beams are off alignment by more than 2 degrees, the transmitted beams will see the wrong receivers and the guard will trip to off.
Cross matrix does not have this problem - each transmitted beam is designed to see all the receivers, so the problem of misalignment is removed completely. Depending on scan distance, SafetyTec guards can be off alignment by as much as 30 degrees or more.
No interface control box required
All SafetyTec light guards, including the Red 4 and Infrascan, are fully contained designs that incorporate all electronics within the transmitter (TX) and receiver (RX) heads. This eliminates the need for any interface control boxes or modules.
The guards are supplied complete with cables ready for termination to the machine. Cables are fitted with standard plug-fit connectors.
