Standard device for double-leaf doors with level of protection IP54

The standard door interlock for double swing doors in level of protection IP54 is equipped with a sealed metal cover and two hard chromed latch bolts to ensure water protection and corrosion protection.



  • metal housing with high stability
  • 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 dirt and dust (at X-dimension 10 mm)
  • constrained faulty closure at DLF2 for use in passenger lifts
  • contacts with solid fine silver plating for a reliable function even at low voltages and currents
  • auxiliary switch as normally closed and/or normally open contact with two galvanically isolated contacts possible
  • extensive range of accessories

special features:

  • water protection (IP54) at horizontal installation position
  • for double-leaf doors with two latch bolts for installation in the door post
  • metal cover with rubber seal instead of transparent cover
  • chromed latch bolt for better oxidation protection
  • terminal block with all electrical connections
  • connection for bowden cable or cable pull for actuation for unlocking available, e.g.
    application 1:unlocking from the pit ladder (< 1.80 m according to EN 81-20)
    application 2:offset emergency release triangle (< 2 m according to EN 81-20)
    application 3:actuation by bowden cable as alternative to pull rod
