OEM 500KG Electromagnetic Lock 12/24V DC Fail-Safe

OEM 500KG Magnetic Lock

The OEM 500KG Electromagnetic Lock delivers high-security door retention through a powerful magnetic field generated by a precision-wound copper coil. This hardware integrates directly with standard access control systems to secure heavy-duty commercial entry points. The internal circuitry supports dual-voltage inputs, allowing field technicians to select between 12VDC and 24VDC operation based on site power availability. This unit operates on a fail-safe principle. It requires continuous power to remain locked. In the event of a power failure or fire alarm trigger, the magnetic bond breaks immediately to allow emergency egress. The device utilizes high-grade silicon steel laminations in the core to maximize flux density and minimize power consumption. This design ensures the armature plate remains securely attached under significant physical pressure.

Key Features

• High-Capacity Holding Force
  The unit provides 500 kilograms or approximately 1100 pounds of static holding strength to resist forced entry attempts.

• Advanced Material Construction

  • Anodized aluminum housing provides high corrosion resistance for long-term deployment.
  • Zinc plating on the armature plate prevents oxidation in humid environments.
  • The E-shaped core utilizes high-permeability magnetic steel for consistent performance.

• Field-Selectable Voltage
  Internal jumpers allow switching between 500mA current draw at 12VDC and 250mA draw at 24VDC.

• Safety and Compliance Features

  • Built-in Metal Oxide Varistor surge protection prevents damage from back-EMF voltage spikes.
  • Anti-residual magnetism design includes a spring-loaded kick-off button on the armature plate.
  • Fail-safe logic ensures the door unlocks during power loss to meet fire safety codes.

Installation requires precise alignment between the magnet face and the armature plate to ensure maximum surface contact. Any gap or misalignment significantly reduces the effective holding strength of the magnetic bond. This locking hardware supports various mounting configurations including L-brackets for out-swinging doors and Z-brackets for in-swinging applications. The internal potting compound protects the electrical components from vibration and environmental moisture. Additionally, the unit features a status LED or bond sensor output to provide real-time feedback to the monitoring station or security panel. This ensures the system controller can verify if the door is physically secured or merely closed.
