Description
Value Series Electromagnetic Door Lock
The Hikvision DS-K4H258S is a single-leaf electromagnetic lock that holds a static linear thrust of 280 kg (617 lb). Current interruption releases the armature plate, and a green LED reports lock status.
The lock body measures 238 × 45 × 25 mm and the armature plate 182 × 38 × 12.5 mm. A 12 VDC supply draws 340 mA per coil, and the unit also accepts 24 VDC input. Total weight reaches 2.1 kg.
Hard anodised aluminium forms the shell, with a nickel-plated lock body and zinc-plated armature plate. An internal MOV and anti-residual magnetism design protect the coil. The lock fits wooden, glass, metal and fireproof doors.
Key Features
280 kg Holding Force
The magnet delivers 280 kg (617 lb) of static linear thrust across the full armature contact face.Dual Voltage Input
The coil runs on 12 VDC by default and accepts 24 VDC for longer cable runs from the power supply.Electrical Specification
- 12 VDC, 340 mA × 2 coil current draw
- Fail-safe release on current interruption
- Green LED indicates working status
Anti-Residual Magnetism
A built-in circuit collapses the field at power loss so the armature releases without sticking to the body.Surge Protection
An internal metal oxide varistor clamps voltage spikes on the lock supply line.Corrosion-Resistant Finish
Hard anodising on the aldural shell, nickel electroplating on the body and zinc plating on the plate resist wear.Door Compatibility
The lock mounts on single-leaf wooden, glass, metal and fireproof doors in access-controlled openings.

Why Choose This Value Series Lock
The fail-safe coil releases on power loss, which suits fire egress paths.
280 kg of holding force secures standard single-leaf openings without a door strike.
The electromagnetic lock has no moving parts, so mechanical wear does not affect service life.
12 VDC and 24 VDC support lets installers match the existing access control power supply.
A 2.1 kg assembly reduces load on glass door frames and slim metal sections.
The green status LED speeds up fault finding during commissioning and maintenance.
