The non-contact safety switches are designed for mounting on movable protective guards (hoods, hinge switches, doors, etc.). Evaluation takes place, for example, via the SIRIUS 3SK safety relay or the SIRIUS 3RK3 modular safety system, compatible with the SIMATIC PLC. They have a particularly high level of protection against interference, manipulation and the environment thanks to various coding variants and feature safety level SIL 3 and protection class IP 69.
SIRIUS 3SE63 non-contact safety switches, RFID
Ideal for metal-working machines and plants thanks to RFID transponder rather than magnet technology
Several RFID switches can be connected in the same safety circuit thanks to integrated crossover, open circuit and external voltage monitoring
Long service life due to wear-free switching
Increased plant availability thanks to extensive diagnostics functions
Optional magnetic catch (18N) prevents unintentional opening
Can be adjusted quickly through a larger switching displacement than mechanical switches and boundary detection by LED indication on the switch
