Electromagnetic Lock ZE-280-5 by No name — model ZE-280-5

Electromagnetic lock ZE-280-5 by No name is a fail-safe holding device that secures doors by means of an electromagnet and an armature plate. Designed for integration with access control systems, the ZE-280-5 provides a straightforward solution for securing office, commercial or light industrial entrances where continuous holding force while energized is required. The unit is intended for installation on door frames and mating armature plates on doors; when power is supplied the magnet attracts the plate to maintain the door in a locked state.

Advantages

The ZE-280-5 offers a compact footprint and a simple operating principle that facilitates integration with existing access control panels, push-button releases, or emergency release circuits. Its electromagnetic operation delivers immediate locking and release with the presence or removal of power. Because it is a non-mechanical latch, the device reduces wear from repeated cycles and requires minimal routine maintenance when installed correctly.

Suitable for

• Office entrance doors integrated with access control systems
• Commercial premises such as retail and service locations
• Internal doors in light industrial facilities where controlled access is needed
• Doors requiring fail-safe unlocking on power loss or when connected to emergency release circuits

Key specifications

• Operating principle: electromagnet with armature plate
• Mounting: frame-mounted magnet with door-mounted armature plate
• Intended use: fail-safe holding when energized (unlocks on power loss)
• Integration: compatible with access control panels, push-button releases and emergency circuits
• Typical applications: office, commercial and light industrial doors

How to use

Install the magnet on the door frame and fix the armature plate to the door so that the surfaces align precisely when the door is closed. Connect the lock to a suitable power supply and to the access control or release circuitry according to wiring requirements; the unit secures the door when power is present and releases when power is removed or when the release circuit is activated. Ensure electrical connections and mounting fasteners are tightened to the manufacturer’s torque recommendations and that any supplementary sensors or door position switches are configured for reliable operation.

Usage recommendations

For reliable performance, verify that the magnet and armature plate surfaces are clean and free from debris, confirm correct alignment during installation, and use a regulated power supply matched to the lock’s electrical requirements. Where building codes require, integrate the lock with emergency egress wiring and test periodic operation as part of routine access control maintenance.
