Product Features

Dual 280 kg Holding Force

The DS-K4H258D provides a static linear holding force of 280 kg (617 lbs) per door, delivering a combined high-strength locking solution for double-door installations requiring reliable access control.

Designed for Double-Door Applications

Specifically engineered for double-door configurations, this magnetic lock is ideal for securing main entrances, office access points, emergency exits, and other high-traffic entryways.

Fail-Safe Electromagnetic Operation

The lock automatically releases when power is interrupted, ensuring occupants can exit safely during emergencies while complying with fail-safe access control requirements.

Anti-Residual Magnetism Technology

Advanced anti-residual magnetism prevents the armature plates from sticking after power is removed, allowing smooth and reliable door release while reducing wear over time.

LED Lock Status Indicators

Integrated green LED indicators provide a clear visual display of the operating status for both magnetic locks, simplifying monitoring and maintenance.

Durable Industrial Construction

Manufactured with a hard-anodized aluminum shell and eco-friendly plated lock body and armature plates, the DS-K4H258D is built to withstand continuous operation in demanding environments.

Wide Door Compatibility

The magnetic lock is suitable for wooden, glass, metal, and fire-rated doors, providing installation flexibility across a wide range of commercial and residential applications.

Integrated Surge Protection

Built-in MOV (Metal Oxide Varistor) surge protection helps protect the lock from voltage spikes, enhancing system reliability and extending service life.

Low Maintenance Design

With no moving mechanical components, the electromagnetic locking mechanism minimizes wear and maintenance requirements while providing consistent locking performance.

Seamless Access Control Integration

The DS-K4H258D integrates effortlessly with Hikvision access control terminals, video intercom systems, card readers, exit buttons, and third-party access control platforms to create a complete electronic security solution.
