QOLTEC 52459 Electromagnetic Lock 12V Symmetrical with Memory and Interlock

Electromagnetic lock QOLTEC 52459 12V symmetrical with memory and lock is a compact locking device designed for access control and door security systems. Operating at 12 volts, the lock features a symmetrical body for reversible mounting and built-in memory and lock functions that preserve the last state of the device. Intended for installations where a consistent holding force and state retention are required, this model integrates into commercial and residential setups that use electromagnetic locking principles.

Advantages

The symmetrical design allows reversible installation on left- or right-handed doors without mechanical modification. Built-in memory and lock functions retain the lock state after power interruptions or control signal changes, supporting reliable access management. Compatibility with standard 12V power supplies simplifies integration into existing electrical systems, and the compact form factor supports installation in confined frames or mounting points.

Suitable for

• Access control systems in offices and commercial buildings
• Residential entrance and interior doors requiring secure magnetic locking
• Retrofit installations where reversible mounting is needed
• Doors controlled by keypads, card readers, or centralized security systems

Key specifications

• Operating voltage: 12 V DC
• Symmetrical body for reversible mounting
• Built-in memory and lock functions for state retention
• Designed for electromagnetic holding force applications
• Compact form factor suitable for standard door frames

How to use

Mount the electromagnetic lock QOLTEC 52459 on the door frame according to the door swing direction, taking advantage of its symmetrical construction for left or right mounting. Connect the device to a 12 V DC power supply and to the access control system outputs (e.g., keypad, card reader, or central controller) following standard wiring practices for electromagnetic locks. Verify the memory and lock functions by testing power interruptions and control signals to ensure the lock retains or releases as required by the installation logic. Adjust alignment between the armature plate and the lock face to achieve full contact and optimal holding force.

Recommendations

Use a regulated 12 V DC supply with appropriate current capacity and short-circuit protection. Ensure the armature plate surface and lock face are clean and aligned to maintain maximum holding performance. Integrate the lock with compatible access control components and provide surge protection if the system is exposed to electrical disturbances.
