Description

The DS‑K4H258D is a double‑door electromagnetic (mag‑lock) unit engineered to secure entrances where two leaf doors or heavy doors (wood, glass, metal, or fire‑rated) are used. It delivers a combined static linear holding force of 280 kg × 2 (~617 lbs × 2), ensuring robust locking strength even under force or tampering attempts.

Designed to operate on 12 V DC (with some variants also supporting 24 V DC), DS‑K4H258D uses a reliable current‑interruption unlocking mechanism: when power is cut, the lock releases.  The lock’s body measures 500 × 45 × 25 mm, while its armature plate is 182 × 38 × 12.5 mm, and the total weight is about 4.2 kg — sturdy enough for durable installations.

Additional convenience features include: an LED indicator that shows lock status, abrasion‑resistant materials, and internal surge protection via an MOV (voltage‑dependent resistor).  The DS‑K4H258D is suitable for a variety of door types — wooden, glass, metal, or fire‑rated — making it a versatile, heavy‑duty solution for office buildings, commercial premises, or controlled‑access facilities.
