The YD30M, also known as the Cobalt-mini is a revolutionary low voltage motor driven door lock for 90º swing doors. It has been designed to secure single acting doors and addresses the two biggest issues in door locking; the ability to align a misaligned door and the ability to release when requested, even with excessive load on the door. The Cobalt successfully overcomes these issues and does it all within a very small footprint whilst still offering the user an array of other features that include;

  • Door misalignment of 8mm is automatically corrected.
  • Will pull a door into a secured position against a seal.
  • Releases instantly when requested even with 100kg side load on the door.
  • Less than 50mA standby current.
  • Monitoring of both Door and Bolt positions.
  • Voltage input of 12 – 24VDC can be supplied.
  • On site conversion from Fail Safe to Fail Secure.
  • Stainless Steel parts are used throughout the lock.
  • Holding force of 10,000N with an automatic deadbolting pin.
  • Integrated access control that offers multiple attempts to lock and unlock, anti-tamper and auto-relock.

The Cobalt is typically used in commercial doors and controlled by access control systems. This gives the user the ability to control access in and around a facility and provide traffic reports when desired. Additionally the Cobalt can be used in a simpler system where just controlling access to a single door can be implemented with a stand-alone access system. Given its small size yet strong and reliable operation the Cobalt is suited for most single acting door applications.
