Standard device with level of protection IP54, vertical installation

For vertical installation we offer the door interlock DL(F)1 also in level of protection IP54 as special version DL(F)1-WV. To ensure the water protection, the DL(F)1W is equipped with a sealed metal cover and a hard-chrome plated latch bolt for better 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 DLF1-WV 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 contact and/or normally open contact with two galvanically isolated contacts possible
  • extensive range of accessories

Special features:
  • waterprotection (IP54) at vertical installation position in the door frame (-WV)
  • 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 or 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
