Safety light curtains cope with arduous environments

Trouble-free performance is complemented by a choice of four standard resolutions - 20, 30, 40 or 90mm – making the Solid 4E an extremely versatile safety light curtain for hazardous point protection or area protection across many diverse applications. These can include finger and hand protection at presses and stamping machines for the metal, leather and plastic industries, or at manual insertion areas of automated manufacturing cells.

Where multiple light curtain guarding requirements are needed in close proximity, the Solid 4E is said to be in a field of its own, since it incorporates two different and adjustable light-beam codings. This eliminates potential optical cross-talk between neighbouring devices, thereby ensuring completely reliable safety protection

Standard functions include restart interlock and relay monitoring, and the Leuze Mayser MSI series intelligent interface devices can extend the functionality to cover muting, single/double break, or the connection of safety switches.

Another big benefit with Leuze Mayser's new Solid 4E safety light curtain is maintenance-free operation due to the fail-safe OSSD transistor output. Various LEDs and a digital display indicate the OSSD status, report weak reception signal and help make adjustments or quickly perform fault diagnostics on site.

In developing the Solid 4E, Leuze has created a product range that will give lower cost of ownership in terms of performance, easier installation and trouble-free operation.
