Lockwood Padde PD-770300-012 Z4 Mini Mag

280kg, Single Monitored, PTL, Surface Mount, 12/24V DC



  • Fail-safe: unlocks when power is removed
  • Easy installation: suitable for both new and retrofit usage
  • High holding force: refer to the technical data overleaf
  • Self-alignment: armature plate pivots to accommodate door drop
  • Silent operation: no humming or buzzing
  • Dual voltage: site selectable 12 or 24 Vdc
  • Monitoring: Reed Switch monitoring on all models.
  • Hall-Effect monitoring on Z4 and Z8 models.
  • Instantaneous release: smart electronics on the Z Series Electromagnets eliminate residual magnetism
  • Monitoring – Hall/Bond Monitoring This indicates that the lock is powered and that the armature plate is in position and magnetically bonded (it monitors if the magnet is locked)
  • Reed switch monitoring An integrated reed switch monitors the door position separately (it monitors the position of the door)
