Air Shower Magnetic Lock
A compact electromagnetic lock and armature set that holds an air shower door closed during controlled entry and purge sequences.
- Fail-Safe Magnetic Holding
- Matched Armature Plate
- Compact Surface Mounting
- Interlock-Control Compatible
Product Introduction
The air shower magnetic lock uses an energized electromagnetic body and a matching armature plate to hold a swing door during the controlled shower sequence. With no projecting latch bolt, the paired surfaces release cleanly when power is removed and suit frequent automated cycling. The aluminum housings provide a compact, corrosion-resistant assembly for mounting above or beside the door. Replacement work should match holding requirement, supply voltage, available mounting space, cable routing and controller logic.
Key Features
Fail-safe operation releases the door when lock power is removed.
Compact rectangular components fit narrow air shower headers and frames.
A protected lead connection supports integration with the door-interlock controller.
Customer Product Concerns
Stable magnetic holding depends on correct plate alignment, electrical compatibility and full face contact when the door closes.
A misaligned armature plate reduces the usable magnetic holding force.Matched component dimensions and adjustable mounting permit full pole-face contact.
An incompatible supply voltage can overheat or under-energize the coil.The lock coil is selected for the existing controller output and wiring system.
A bulky latch conflicts with the narrow cleanroom door frame.Low-profile surface-mounted magnet and plate components use limited header space.
Exposed cable entry is vulnerable during cleaning and maintenance.A dedicated gland protects the lead where it exits the magnet housing.
Typical Applications
