Cleanroom Doors, Windows and Interlock Systems
Cleanroom Electromagnetic Door Lock
A surface-mounted electromagnetic lock that secures cleanroom doors without a projecting mechanical latch and releases automatically when power is removed.
- Up to 510 kg Holding Force
- Fail-Safe Release
- Lock Status Monitoring
- Low-Profile Housing
Product Introduction
The cleanroom electromagnetic door lock combines a continuously energized steel magnet with a floating armature plate fixed to the door leaf. When the door closes, the armature self-aligns against the magnet face to develop uniform holding force without an exposed bolt entering the frame. A monitored configuration can report locked or unlocked status to the access-control system, while the anodized aluminum or stainless enclosure presents a smooth surface around the header.
Key Features
Selectable 12 or 24 VDC operation integrates with common access-control power supplies.
A built-in bond sensor can provide a dry-contact indication after magnetic holding is established.
The fail-safe principle releases the opening when controlled power is interrupted.
Customer Product Concerns
A cleanroom access lock must hold reliably without adding dirt-trapping latch pockets or interfering with emergency power-release logic.
Mechanical latches can create exposed recesses around the frame that are difficult to wipe.The magnet and armature use flat external faces with no bolt pocket in the clean opening.
Door flex or slight misalignment reduces the contact area of a rigid magnetic plate.A pivoting armature assembly self-aligns against the energized magnet face.
The control system cannot distinguish a closed door from a securely bonded lock.Optional bond and door-position contacts provide separate feedback signals.
Typical Applications
Personnel airlock doorsCleanroom corridor access pointsLaboratory controlled entrancesInterlocked material transfer doors
