The innovative SIRIUS 3SE5 position switches are modern in design, compact, modular and simple to connect. They save time and increase flexibility during installation of a whole range of switch variants. In principle it is possible to combine any enclosure with any operating mechanism, paying due consideration to the EN 50041 and EN 50047 standards where necessary.

  • All actuators can be turned around the axis in increments of 22.5 deg
  • Rounded and roller plungers according to EN 50041 with 3 mm over travel (total travel 9 mm) for greater tolerance when switching
  • All enclosure variants have an integrated chlorinated rubber diaphragm for high functional safety in cold and aggressive environments
  • The short stroke contact block 1NO+1NC improves the precision of the switching operation through a reduced actuation path
  • The contact block with 1NO+1NC snap action contacts with 2 mm contact opening is suitable for simultaneous shutdown and signaling, particularly in the elevator industry
  • 15000000 typical, 100000 electrical endurance, 10000000 electrical endurance with contactor switching cycles
