Product Description

280KG Concealed Magnetic Lock - Product DetailsThis 280KG concealed magnetic lock is a high-performance security solution designed for hidden installation, ideal for commercial, residential, and industrial door access control systems. It combines strong holding force with a discreet design—eliminating visible hardware to preserve door aesthetics while ensuring reliable anti-theft and anti-unauthorized entry protection. Suitable for metal, wood, and composite doors, it integrates seamlessly with most electronic access control setups (e.g., card readers, biometric scanners, keypads).Specification Key Features1.Strong & Reliable Holding Force: 280KG magnetic force securely locks doors, preventing prying or forceful entry—suitable for high-traffic or high-security areas (offices, warehouses, data centers).
2.Concealed Design: Mounts hidden inside door frames or door leaves, no visible locks/hardware. Maintains the original appearance of doors, perfect for spaces prioritizing aesthetics (retail stores, hotels, art galleries).
3.Durable & Weather-Resistant: Aluminum alloy shell resists corrosion and wear; IP54 rating protects against dust and splashes, ensuring long-term use in indoor, semi-outdoor, or humid environments (e.g., underground garages, covered gates).
4.Easy Integration: Compatible with 12V DC access control systems, including card readers, biometric devices, exit buttons, and remote controls. Supports both automatic and manual door operation.
5.Low Maintenance & Safe: No mechanical wear parts (reduces repair needs); built-in overcurrent protection to avoid damage from voltage fluctuations. Complies with [relevant standards, e.g., CE/RoHS] for safe use.

Application ScenariosCommercial Spaces: Office entrances, retail store backdoors, restaurant staff areas, shopping mall access gates.
Industrial & High-Security Areas: Warehouse loading docks, data centers, server rooms, factory restricted zones.
Residential & Public Areas: Apartment main doors, villa gates, school classrooms, hospital nurse stations.
