Electromagnetic Lock: How a 280KG Maglock Secures Glass and Fire Doors
For offices, shops and commercial buildings, few locks are as discreet as an electromagnetic lock. The SK-280 electromagnetic lock holds doors with 280kg / 600lbs of magnetic force and releases instantly when you cut power.
Three Models, One Door Solution
Pick the 2-wire standard model for simple release with an indicator light, the 5-wire feedback model for door status and alarm signals, or the fully sealed waterproof model for outdoor use.
Fail-Safe by Design
Power loss means the lock opens — that is the fail-safe rule behind every fire code. When the fire alarm cuts the circuit, doors release automatically so people can exit. No keys, no panic bars, no obstruction.
Built to Hold and Built to Last
The magnesium-aluminum alloy body is sandblasted, anti-rust and scratch-resistant, with holding force verified by pull tests. Five-wire sealed wiring resists water damage, and the slim 250 x 48 x 28mm body mounts neatly on door frames.
Where the SK-280 Works Best
- Glass doors – invisible lock line on aluminum frames.
- Fire-rated doors – fail-safe release in emergencies.
- Offices and commercial buildings – pairs with access controllers and card readers.
- Wood and metal doors – universal mounting kit.
