Electromagnetic door latch No name R3-12.11L — electrically operated locking device for doors and gates

Electromagnetic Door Latch No name R3-12.11L is an electrically operated locking device intended for securing doors and gates as part of access control systems. When energized it provides a magnetic holding force that keeps a door closed; when power is cut the latch releases to allow exit. The latch is designed for integration with remote control, card readers, intercoms or building management systems and is suitable for both interior and sheltered exterior entrances where controlled locking is required.

Advantages

The latch offers reliable electromagnetic locking with rapid response to electrical control signals and simple mechanical mounting for retrofit or new installations. Its design enables seamless connection to standard access control wiring and provides a fail-safe release when power is removed. The device supports continuous hold under supply voltage and reduces mechanical wear compared with purely mechanical locks.

Suitable for

• Office and commercial interior doors integrated with access control
• Apartment building entry doors with remote release
• Server rooms and restricted areas requiring controlled access
• Gates and secondary exterior doors in sheltered locations

Key specifications

• Operating principle: electromagnetic holding and release
• Intended use: electrically controlled door latch for access systems
• Installation: surface or recessed mounting options depending on frame and door
• Power supply: designed for continuous energized operation (connect to compatible voltage source)
• Environment: suitable for indoor use and sheltered outdoor locations
• Control interface: compatible with typical access control triggers (switch, relay, reader output)

How to use

Mount the electromagnetic latch to the door frame following the mechanical alignment requirements so the armature plate mates flush with the magnet when the door is closed. Connect the power leads to the access control supply and control output, ensuring correct voltage and polarity per system specifications. Test energizing and de-energizing cycles to confirm secure holding and reliable release. Incorporate appropriate safety wiring such as monitored door contacts or fail-safe circuits where required by your access control policy.

Usage recommendations

Use the latch with a properly rated power supply and compatible access control hardware. For exterior installations select sheltered mounting locations and ensure regular inspection of the mating surfaces for dirt or corrosion to maintain full holding force. Implement a backup power or fail-safe plan for emergency egress and coordinate with local safety codes.
