  • transparent cover for optimal function control
  • silent due to buffers in both directions
  • maintenance-free by permanent lubrication with high quality lubricants (up to -30 °C)
  • oiled felt ring at latch bolt for lubrication as well as for sealing against dust and dirt (at X-dimension 10 mm)
  • constrained faulty closure at DLF2 for use in passenger lifts
  • auxiliary switch as normally closed contact and/or normally open contact with two galvanically isolated
  • contacts possible
  • contacts with solid fine silver plating for a reliable function also at low voltages and currents
  • extensive range of accessories

special features:

  • two latch bolts for double-leaf doors
  • terminal block with all electrical connections
  • optional: separate door switches for monitoring the closing position of both door leafs
  • reduced wiring due to internal series connection of the contacts for locking mechanism and the optional door switches
