SICK Magnetic Safety Switches The RE1 and RE2 series from SICK are compact non-contact safety switches with a long service life thanks to the 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. Up to performance level PL e / Cat. 4 (EN ISO 13849) Sensors with plug connector or connected cable Flexi Loop-compatible M12 plug connector High tolerances for door misalignment Glass-fiber reinforced PPS rectangular housing Both RE1 & RE2 are supplied with a switch and actuator offering significant cost saving Spare actuators are also available separately RE1 Response range of up to 7 mm 1 NO/1 NC or 2 NO contacts RE2 1 NO/1 NC, 2 NO contacts or 3 NO contacts Fast diagnostics via LED status indicator (RE27) Note The actuators are only coded in the sense that they have an identical magnetic combination making them type specific not individual example specific.
