Uniview OEA-ML22-280 Double Door Magnetic Lock, 280kg

The Uniview OEA-ML22-280 secures a double-leaf door from one 500mm housing, with 280kg holding force and a lock status output. It fits main entrances, showrooms, clinics and double glass doors.

====

A double-leaf entrance needs a lock that holds both leaves at once, and that is the job of the Uniview OEA-ML22-280. One 500mm aluminum alloy housing mounts at the center of the top frame, with an armature plate on each leaf, and it holds with 280kg of force. It runs on 12V or 24V DC and also appears as UNV OEA-ML22-280. Typical homes for it are company receptions, showrooms, clinics and double glass doors in office fit-outs.

Uniview OEA-ML22-280 specifications

• Holding force: 280kg.
• Power: DC12V or DC24V.
• Current: 460mA x 2 at 12V or 230mA x 2 at 24V, since the housing contains two magnets.
• Lock housing 500 x 47.7 x 27.5mm; armature plate 180 x 38 x 11.7mm.
• Weight: 4kg.
• Operating range: -30°C to +60°C, humidity up to 95%.
• Certifications: CE, FCC, RoHS.

Lock status output for your access system

This model provides a lock status signal output. Wire it to an input on the access controller and the system can tell whether the plates have actually bonded to the magnet. In practice that means a door left ajar after someone walks through, or a forced door, shows up in the system instead of going unnoticed.

Built-in protection

• MOV surge protection absorbs the voltage spike created when the coil switches off, protecting the controller output.
• No residual magnetism, so the plates release the instant power drops.
• Double insulated, abrasion resistant lock body.
• Tamper-proof screws make it harder to remove the lock.

What fail-safe means for your entrance

The lock holds only while powered and releases during a power cut. Size the supply for both magnets plus the controller: at 12V the whole lock draws 920mA, close to 1A, and at 24V it draws 460mA. Add battery backup if the entrance must stay locked when mains power drops.

Where it fits in Saudi Arabia

• Corporate main entrances: staff badge in or use face recognition, and reception releases the door for visitors.
• Showrooms: lock the double glass front after business hours from the controller.
• Clinics and medical complexes: separate the waiting area from internal corridors.
• Hotels: the door to the admin offices or the guest gym, opened with a staff or guest card.
• Residential buildings and compounds: tie it to the intercom so residents open the lobby door from their monitor.

Brackets for the ML22

For the long lock body, Uniview lists the OEA-MS22-280L bracket (0.54kg), which is different from the single-door OEA-MS12-280L. For the armature plates, choose one type: the OEA-MS12-280Z Z-bracket, or the OEA-MS12-280U U-bracket for 8 to 12mm frameless glass doors.

OEA-ML22-280 or OEA-ML12-280?

Holding force and voltage are the same. The ML22 covers two leaves with a 500mm, 4kg housing. The ML12 secures one leaf with a 2kg housing and draws half the current. For a single door, the ML12 is enough.

Frequently Asked Questions

Is one lock enough for a double door?

Yes. The OEA-ML22-280 is a single 500mm housing with two magnets, and each leaf gets its own armature plate.

What is the lock status output for?

Wire it to your access controller so the system knows whether the door is secured and can flag a door left open or forced.

Does the OEA-MS12-280L bracket fit it?

No. Uniview lists the OEA-MS22-280L for this lock body. For the armature plates, use the OEA-MS12-280Z or OEA-MS12-280U.

Features

• One 500mm housing rated at 280kg holding force: locks both leaves instead of fitting two separate locks.
• Lock status output: the controller knows whether the door is actually secured and can raise an alarm.
• MOV surge protection: suppresses the voltage spike when the coil is switched off.
• No residual magnetism: the plates release the moment power is cut, so the door never sticks.
• Tamper-proof screws and double insulation: harder to remove from outside, rated for -30°C to +60°C operation.
