Product Features

Strong 280 kg Holding Force

The magnetic lock delivers a maximum static linear holding force of 280 kg (617 lbs), providing secure locking performance for single-door access control applications.

Compatible with Multiple Door Types

Designed for versatile installations, the DS-K4H258S supports wooden doors, glass doors, metal doors, and fireproof doors with a 90° opening angle, making it suitable for a wide range of commercial and residential environments.

Fail-Safe Electromagnetic Operation

The lock releases automatically when power is interrupted, ensuring compliance with emergency exit requirements and improving occupant safety during emergencies.

Anti-Residual Magnetism Design

An anti-residual magnetism feature prevents residual magnetic force after unlocking, allowing the door to open smoothly while reducing wear on the locking mechanism.

LED Lock Status Indicator

An integrated green LED indicator provides a clear visual indication of the lock’s operating status, simplifying monitoring and maintenance.

Durable Construction

Manufactured using abrasion-resistant materials with a hard anodized aluminum shell and corrosion-resistant plated components, the lock is built for long-term reliability and continuous operation.

Flexible Power Input

The magnetic lock supports both 12 V DC and 24 V DC power supplies, with 12 V DC configured as the default operating voltage, providing flexibility for different access control installations.

Easy Integration with Access Control Systems

The DS-K4H258S integrates seamlessly with Hikvision access control terminals, video intercom systems, card readers, exit buttons, and third-party controllers, making it ideal for complete electronic door security solutions.

No Mechanical Wear

Because the lock operates using electromagnetic force rather than moving mechanical components, it minimizes wear and reduces maintenance requirements, extending product lifespan.
