180kg / 350lbs Single Door Electromagnetic Lock (12V DC, Fail-Safe)

Product Overview

The LM-1802 Single Door Electromagnetic Lock is a compact, surface-mounted access control locking device engineered for interior doorways, office entries, and light commercial security installations. Operating on a fail-safe principle (de-energizes to unlock when power is removed), this magnetic lock guarantees life-safety compliance, ensuring uninhibited egress during emergency power outages or fire alarm activations.

Constructed from premium anodized aluminum paired with high-permeability magnetic steel laminations, the LM-1802 delivers a reliable holding force of 180 kg (350 lbs) with zero mechanical friction, latch wear, or residual magnetism. Designed for standard 12V DC operation, it features integrated metal oxide varistor (MOV) surge suppression to safeguard access controllers and auxiliary power units against voltage spikes. It is ideal for securing wooden doors, narrow-stile aluminum doors, interior glass doors, and light metal partitions across commercial, institutional, and residential facilities.

Key Features

• 180 kg (350 lbs) Holding Force: Delivers continuous magnetic clamping resistance to prevent forced physical entry on light to medium interior doors.

• Fail-Safe Operation: Releases immediately upon loss of power to satisfy emergency exit and life-safety building code regulations.

• Dedicated 12V DC Powering: Operates efficiently on standard 12V DC security power supplies with a low current draw of approximately 300–380mA.

• Anti-Residual Magnetism Design: Built-in spring-loaded release pin prevents residual magnetic pull, ensuring instantaneous door separation when de-energized.

• Integrated Surge Protection: Internal MOV (Metal Oxide Varistor) protects interconnected access controllers and relay boards from back-EMF spikes.

• Durable Anodized Aluminum Housing: Sandblasted aircraft-grade aluminum alloy body provides superior wear and corrosion resistance.

• Broad Mounting Bracket Compatibility: Easily pairs with dedicated L-brackets (LMB-180L), Z-brackets (LMB-180Z), and U-brackets for inswing, outswing, and frameless glass door applications.
