Retiring cam with motorized actuation RKMO

The retiring cam RKMO operates motor driven and convinces of a barely perceptible noise when unlocking and locking. It is available as 24 V DC version or with 100-250 V DC/AC wide-range voltage input. This new motorized retiring cam is also characterised by a low power consumption, high actuation force and a large adjustable stroke.


  • drive with maintenance-free three-phase motor
  • high actuation force up to 65 N
  • especially low total height of only 50 mm
  • large stroke up to 50 mm, adjustable
  • energy-saving due to low power requirement
    of only 1 A at 24 V and reduced holding current
  • duty cycle of any length (100 % duty cycle)
  • hardly perceptible unlocking and locking
    of the landing doors due to low noise emission
