Flattest device with motorized actuation and UL-certification

The CL(F)MO-UL has a low overall height and is unlocked with an integrated electric motor. The energy-saving motor has a high starting power and operates almost silently. The lock is UL approved for use in private residential lifts on the North American market.



  • metal housing with high stability
  • silent due to buffers in both directions
  • maintenance-free by permanent lubrication with high quality lubricants
  • constrained faulty closure at CLFMO for use in passenger lifts
  • contacts with solid fine silver plating for a reliable function even at low voltages and currents
  • extensive range of accessories

special features:

  • European and UL certification for North America
  • integrated actuation by maintenance-free, low-noise three-phase motor and braked dropping of the bolt
  • patent protected by Gbm DE 20 2015 105 331 and by patent EP 3 153 454 B1, validated in DE / FR / IT / ES
  • low pull-in current (< 1 A at 24 V)
  • automatic switching over to reduced holding current (0.2 A), energy saving
  • safe unlocking by position monitoring even if the bolt is temporarily blocked (incorrect operation)
  • status display by coloured LED’s
  • symmetrical fixing dimensions and centrically arranged latch bolt
  • low construction height
  • reduced bolt stroke
  • integrated auxiliary switch (always existing)
  • optional: patented monitoring of the base side emergency release with positive opening safety switch (EN 81-21)
  • same position of the emergency release triangle also indirect with monitoring
  • lever for self-liberation (manual operation) from the pit and preparation for external cable pull always existing
