"The RE1 and RE2 series from SICK are compact non-contact safety switches that offer a long service life thanks to their durable and low maintenance design. Just one of these safety switches, in conjunction with a suitable safety module, makes it possible to solve applications up to PL e and Cat. 4 (EN ISO 13849). These magnetic switches are easy to clean, making them suitable for contaminated areas or environments with strict hygiene standards. Flexi Loop now enables a safe series connection with enhanced diagnostics capabilities and minimal wiring effort.Supply Voltage = 30 V dcSafety Contacts = NCHousing Material = PlasticAuxiliary Contacts = NOConnection Type = M8Switch Type = RectangularTerminal Type = CableSeries = RE11Switching Distance = 12 (Off) mm, 3 (On) mmIP Rating = IP67"
