The Uniview OEA-ML12-280 is a 280kg electromagnetic lock for a single-leaf door, powered from 12V or 24V DC. Use it on office, server room and clinic doors that open by card, face recognition or intercom.
====
The Uniview OEA-ML12-280 is an electromagnetic lock for a single-leaf door, rated at 280kg of holding force. Its housing is high-strength aluminum alloy, it runs on 12V or 24V DC, and Uniview lists it for wooden, glass, metal and security doors. You will also see it sold as UNV OEA-ML12-280. Put it on an office entrance, a server room or a clinic door that should open by card, face recognition or a tap on the intercom screen instead of a key.
Uniview OEA-ML12-280 specifications
A maglock has two parts. The magnet housing mounts on the door frame, and the steel armature plate mounts on the door. With power applied, the plate bonds to the magnet and the door stays shut until the controller cuts the current.
- Holding force: 280kg.
- Power: DC12V or DC24V.
- Operating current 460mA; standby current 460mA or 230mA.
- Weight: 2kg.
- Operating range: -30°C to +60°C, humidity up to 95%.
Fail-safe: the door opens if power fails
This lock is fail-safe. It needs constant current to stay locked, so a power cut or a release signal from the controller frees the door immediately. That is the behavior you want on doors people use to leave a building, such as office entrances and corridors. If the door must stay secure during an outage, plan a power supply with battery backup that feeds both the lock and the controller.
Surface mounting, no cutting
There is no latch, strike or mortise to cut. The housing fixes to the top of the frame and the armature plate fixes to the door directly opposite it. When the door layout does not allow that, Uniview offers three brackets for this model:
- OEA-MS12-280L: L-bracket for the lock body, 0.27kg.
- OEA-MS12-280Z: Z-bracket for the armature plate, 0.48kg.
- OEA-MS12-280U: U-bracket for the armature plate on 8 to 12mm frameless glass doors, 0.32kg.
Typical uses in Saudi Arabia
- Office and branch entrances opened by a card reader or face terminal.
- Server rooms and archive rooms restricted to authorized staff.
- Clinics, where reception releases the door to the treatment area with a button.
- Villas and residential buildings, with the entrance released from the indoor intercom monitor.
Wiring to controllers and intercoms
Connect the lock to the lock output of an access controller or an outdoor intercom station. Before installing, check two things: that the power supply delivers 12V or 24V with enough current for both the lock and the controller, and that the output is set to cut power on release, as fail-safe operation requires. The lock carries CE, FCC and RoHS certifications.
OEA-ML12-280 or OEA-ML22-280?
Both hold 280kg and accept the same voltages. The OEA-ML12-280 secures one door leaf and weighs 2kg. The OEA-ML22-280 covers double doors with a single 500mm housing, weighs 4kg and draws twice the current (460mA x 2). Pick the ML12 for an office or room door and the ML22 for a double-leaf main entrance.
Frequently Asked Questions
Does the lock release during a power cut?
Yes. It is fail-safe: it only holds while powered, so the door opens when power is lost.
Can I install it on a glass door?
Yes. It supports wood, glass and metal doors. For 8 to 12mm frameless glass, mount the armature with the OEA-MS12-280U U-bracket.
What power supply does it need?
12V or 24V DC. Operating current is 460mA, so size the supply for the lock plus the controller.

Features
- 280kg holding force: the door stays shut against normal pushing and pulling while the lock is powered.
- 12V or 24V DC input: run it from the supply you already have; operating current is 460mA.
- Fail-safe operation: the door releases when power is cut, so nobody is trapped behind it.
- Aluminum alloy housing: surface-mounts on the frame with no cutting into the door.
- 3 matching brackets (L, Z, U): fit it to inward-opening doors or 8 to 12mm frameless glass doors.
