Product Description

Technical Information:

The RKMO retiring cam unit is motor-driven and runs almost silent when unlocking and locking. The cam is available in a 24VDC version or as a 100-250VDC/AC wide-range voltage input. This new motorised retiring cam is also characterised by low power consumption, with a high actuation force and a large adjustable stroke. The RKMO can replace the retiring cams types EMT15K, EMT17 and EMT18 with the corresponding mounting kit (see attached data sheet).


  • Drive with maintenance-free three-phase motor
  • High actuation forces up to 65 N
  • Especially low total height of only 50 mm
  • Large stroke up to 50 mm, adjustable
  • Suitable for all Dewhurst Gatelocks.
  • 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 ‚Äč
