Application
SIRIUS 3SE6 magnetically operated switches are designed for
mounting on movable protective guards (hoods, hinged covers,
doors, etc.). Evaluation can be performed by means of a safety
relay or through connection to a bus system.
The 3SE66 non-contact, magnetically operated safety switches
stand out due to their enclosed design with degree of protection
IP67. Since they are coded, they do not have to be concealed
when installed They are particularly suitable therefore for areas
exposed to contamination, cleaning or disinfecting.
A magnetic monitoring system comprises one or more magneti-
cally operated switches and an evaluation unit, e. g. a safety
relay. When contact blocks 1 NO + 1 NC (+ 1 NC signaling
contact) or 2 NC (+ 1 NC signaling contact) are used, the 3SK
safety relay, for example, provides a high degree of protection
against manipulation and can be installed in safety circuits up to
SIL 3 according to IEC 62061 and PL e according to
EN ISO 13849-1.
