QWORK Electric Magnetic Lock, 60kg 130LB
The QWORK single magnetic lock provides 60 kg (130 lbs) of holding force with NC mode, meaning the door remains locked while power is supplied. The compact size (80Lx37.3Wx23.3H mm) fits many standard door frames, and the armature plate measures 74Lx32Wx11H mm. It uses DC12V and draws 0.11A to 0.15A, balancing strength and power usage. A built-in voltage spike suppressor adds security by protecting the circuit from surges.
Best for: Small to mid-size interior doors in homes, offices, or storefronts that require reliable NC locking without external power fail alarms. It’s well-suited for doors where the latch is mounted above the frame for a clean look.
Limitations: The unit is designed for NC operation; if you need a fail-safe lock that unlocks with power loss, this model would not suit that need. Installation assumes a standard door frame top mounting.
QWORK 4 Pack Electric Magnetic Lock, 60kg
This 4-pack version mirrors the single lock’s 60 kg holding force with NC mode, designed for multi-door installations. Each lock operates on DC12V with similar current draw (0.11A ~ 0.15A) and includes a built-in voltage spike suppressor. Mounting is done under the top of the door frame to ensure secure latching.
Best for: Property managers or businesses installing multiple access points; a single purchase covers several doors with consistent performance.
Limitation: When using multiple units, ensure your power supply and wiring are sized to handle the total load, especially if multiple locks are energized simultaneously.
YUHANUS Electric Magnetic Lock, 60KG
This stainless-steel magnetic lock emphasizes security with a 60 kg (130 lbs) holding force and a compact profile. It features NC mode (locked under power) and a small form factor, with dimensions around 80x37x24 mm for the lock and 75x32x11 mm for the armature plate. The unit employs DC12V operation and is designed for doors where a slim, discreet lock is preferred.
Best for: Modern interior doors where a slim, low-profile magnet is desired, including apartments, offices, and retail spaces; ideal when door aesthetics matter.
Caution: Its design prioritizes a secure locked state when powered; consider a fail-safe option if you require power-off unlocking for emergency egress.
FERUERW 600 LBs Magnetic Lock with Z and L Bracket
This model offers 600 lbs of holding force with NC mode and includes Z and L brackets for versatile mounting on various door types. It’s built from robust aluminum with corrosion resistance and low noise operation. A reverse current protection feature adds another layer of safety during operation. Power is DC12V and the lock is suitable for a wide range of door materials, including wood, metal, glass, and fire-rated doors.
Best for: Doors requiring strong security with flexible mounting options, including outdoor or entryways subject to weather when brackets are needed for precise alignment.
Limitation: Greater holding force may require a sturdier frame and careful installation to avoid misalignment over time.
FERUERW 600LBS Magnetic Lock, Electromagnetic Door Lock
Another 600 lbs FERUERW model, this lock emphasizes broad door compatibility with an aluminum hard-anodized housing for corrosion resistance and quiet operation. It supports a wide range of door types (wood, metal, glass, fireproof) and includes reverse current protection for added safety. The lock is designed for reliable, long-term use with DC12V operation.
Best for: Installers seeking a uniform 600 lbs locking solution across multiple door types, particularly where corrosion resistance and quiet operation are priorities.
Limitation: As with heavy-duty locks, ensure the door frame and strike area can handle sustained high holding force to prevent wear over time.
YUANWIN Electromagnetic Lock with Z Bracket
This product delivers a high 1200 lbs (500 kg) holding force, suitable for heavy-duty doors or gates. The stainless steel body and anti-residual magnesium design emphasize security and durability. The lock size is 265 x 75 x 39 mm, with an armature plate of 185 x 60 x 13 mm. It operates in NC mode, locking when power is supplied, and uses DC12V. It includes robust brackets for easy mounting on diverse frames.
Best for: Commercial entrances, industrial doors, or gates where maximum holding force is required and outdoor or high-traffic conditions are expected.
Limitation: The high holding force may demand stronger door frames and precise installation to avoid misalignment under repeated use.
Buying Guide: Choosing the Right 12V Magnetic Lock
- NC vs. Fail-Safe: Decide whether you need NC (lock while powered) or Fail-Safe (unlock when powered). For doors that must remain secured during a power failure, NC is ideal; for safe egress during outages, prefer Fail-Safe models.
- Holding Force: 60 kg (130 lbs) is common for interior doors; 600 lbs and 1200 lbs are designed for heavier doors, gates, or high-traffic entrances. Match the lock to your door type and expected force.
- Door Type Compatibility: Consider wood, metal, glass, and fire-rated doors. Some models include Z/L brackets to simplify mounting on multiple surfaces.
- Power and Wiring: Most models run on DC12V with low current draw. Plan your power supply to support the total load if multiple locks are used together.
- Durability and Exposure: Outdoor or damp environments benefit from stainless steel housings and waterproof designs. Look for corrosion resistance and weather sealing as needed.
- Installation Considerations: Ensure top-frame mounting clears the door hardware and that armature plate dimensions fit your door’s strike area. Brackets should provide solid alignment for reliable latching.
Frequently Asked Questions
- What does NC mode mean on a magnetic lock?
NC stands for normally closed; the lock secures the door when power is supplied and unlocks when power is removed, depending on the design.
- Can a magnetic lock be used outdoors?
Yes, if the model is rated for outdoor use and includes weatherproof housing or seals. Choose models with corrosion resistance and waterproof features for exterior doors.
- What holding force do I need for a residential door?
For most interior residential doors, 60 kg (130 lbs) is sufficient. Higher forces are more common for commercial entrances and gates.
- Is a power surge suppressor important?
Yes. A built-in surge suppressor protects the lock and wiring from voltage spikes, improving reliability.
- How many amps do these locks draw?
Most 12V magnetic locks draw around 0.11A to 0.15A under typical operation, enabling reasonable power supply sizing for multiple units.
