Special_Features

  • All actuators can be turned around the axis in increments of 22.5 deg
  • All contact blocks are replaceable
  • All enclosure sizes - now also including the small enclosure 31 mm W are optionally available with an LED signaling indicator
  • All enclosure versions have an integrated chlorinated rubber diaphragm (high functional safety in cold and aggressive environments)
  • DC-13: 3 A at 24 VDC, 0.55 A at 125 VDC, 0.27 A at 250 VDC, 0.12 A at 400 VDC, AC-15: 6 A at 24/125/240 VAC, 4 A at 400 VAC operating current
  • Elements with 1NO-2NC slow action contacts with make before break and 2NO-1NC
  • Rounded and roller plungers according to EN 50041 with 3 mm overtravel (total travel 9 mm) for greater tolerance when switching
  • The 3-pole contact blocks are available for all enclosure sizes
  • The ASIsafe electric component is integrated for the versions with the AS-Interface connection an additional adapter is not required
  • The contact block with 1NO-1NC snap action contacts with 2 x 2 mm contact opening is suitable for simultane- ous disconnection and signaling, particularly in the elevator industry
  • The modular design of the product range allows a number of versions with a smaller number of bearing types for enclosures and operating mechanisms
  • The plastic enclosure with a width of 31 mm has simple and fast wiring equipment which makes it possible to save from approx 20 to 25 % of the time when connecting
  • The short stroke contact block 1NO-1NC improves the precision of the switching operation through a reduced actuation path
