Electromagnetic Locks

Electromagnetic Locks for Access Control

A Magnalock holds a door closed with an electromagnet on the frame and a steel armature plate on the door. With no moving parts, a maglock is fast to install, very durable in high-traffic openings, and releases instantly when power is cut, which makes it the default locking device for glass storefronts, interior access-controlled doors, and gates. The trade-off is that a maglock is inherently fail-safe, so the door is free whenever power is lost. That shapes where it can be used and what egress hardware has to accompany it.

Surface-Mounted Magnalocks

Surface Magnalocks mount on the header on the secure side of the door and come in three holding forces. The M32 provides 600 pounds for interior rooms and traffic control, the M62 provides 1,200 pounds in a body that fits 2-1/2 inches of flat space for interior, perimeter, and exterior doors, and the M82 series provides 1,800 pounds for high-security openings. Suffix letters add features: F for a face-drilled mounting, B for the BondSTAT magnetic bond sensor that reports whether the lock is actually holding, D for a door position switch, and G for gate conduit fittings, so an M62FGBD is a face-drilled 1,200 pound gate Magnalock with bond sensor and door position switch. EcoMag models such as the M680E and M380E add low-power operation with status LEDs and optional request-to-exit capability.

Shear, Recessed & Specialty Locks

Where a surface lock would be visible or in the way, the SAM shear-aligning Magnalock mounts fully concealed in the header, door edge, or threshold at 1,200 pounds, supporting sliding, in-swing, and out-swing doors, and the smaller SAM2 series provides 600 pounds for cabinets and sliding closet doors. The M34R recesses into the frame to secure sliding doors. For asset protection, the MCL-24 brings 200 pounds of holding force to jewelry cases, gun cabinets, and pharmaceutical storage, while the MM15 combines a magnet with spring-loaded hardened steel jaws for 4,000 pounds of holding force in ultra-high security doors. The M62FG-SASM uses a shock-absorbing strike mount built for gates.

Code Requirements for Egress

Because a maglock prevents the door from opening even from the inside, life safety codes require supporting hardware on doors in a means of egress. Access-controlled egress doors generally need a sensor on the egress side that releases the lock as someone approaches, a manual push-to-exit button near the door that releases it for at least 30 seconds independent of the access control system, and automatic release on fire alarm activation or loss of power. Delayed egress systems, such as the DEM680E Magnalock and IMXDA integrated motion exit delay, hold the door for a short, code-approved delay with a local alarm, and are sold in versions matched to specific local building codes. Confirm the full arrangement with the authority having jurisdiction.
