Description
OEM SM-280-S Electromagnetic Lock
The OEM SM-280-S Magnetic Lock provides 280kg (600lbs) of holding force for high-security access control environments. This electromagnetic device operates on a fail-safe principle, ensuring doors remain unlocked during power loss for emergency egress. It utilizes a precision-wound copper coil to generate a consistent magnetic field. The unit supports dual-voltage inputs of 12VDC or 24VDC to accommodate various power supply architectures. It includes an integrated door position sensor for real-time monitoring. This feedback mechanism uses dry contacts to communicate with external security controllers or alarm systems. The anodized aluminum housing protects internal components from environmental degradation. It features an anti-residual magnetism design to prevent the armature plate from sticking after de-energization.
Key Features
High Holding Capacity
The assembly maintains a 280kg tensile strength rating to resist forced entry attempts on standard commercial doors.Integrated Status Monitoring
- Onboard LED indicates current lock status using red and green visual cues.
- Signal output via NO/NC/COM contacts enables remote door state verification.
Dual Voltage Operation
Internal jumpers allow field selection between 12VDC and 24VDC power inputs to match site specifications.Circuit Protection
- Built-in metal oxide varistor prevents reverse current damage to the access controller.
- Surge protection ensures longevity during electrical fluctuations in the facility.
Durable Construction
The high-strength aluminum alloy shell features a sandblasted finish for enhanced wear resistance.

Why Choose SM-280-S
The anti-residual magnetism spring ensures immediate door release when the access control system cuts power.
Integrated feedback loops eliminate the need for separate door contact sensors on the frame.
The unit withstands extreme temperature ranges from -10 to 55 degrees Celsius for various climates.

I ordered two of these for a client site in Industrial Area. What I like most about this specific SM-280-S model is the feedback signal. Most cheap maglocks don’t tell the controller when the door is actually locked, but this one integrated perfectly with our existing access control system. Delivery within Nairobi was very fast, arrived the same day I sorted the payment. Very reliable for the price.
Kevin Maina (verified owner) –
The signal output is a lifesaver for our office door in Westlands. Now the receptionist can actually see on the control panel if the door is properly latched or if someone left it slightly open. Build quality is solid, though the bracket took a bit of time to align perfectly with our glass door frame.

Strong enough for our main entrance. 280kg is no joke, it holds firm and hasn’t given us any issues since installation.
