Electromagnetic Door Catch No name R3-12.21P — model R3-12.21P

Electromagnetic Door Catch No name R3-12.21P — model R3-12.21P is an electromechanical locking accessory intended to provide controlled holding and release of doors and cabinets when supplied with electrical power. The unit generates electromagnetic force to keep a door or panel closed without mechanical latching, and releases when power is removed or switched according to the chosen control scheme. It is designed for straightforward retrofit or new-install installations in furniture, small access points and automatic door systems.

Advantages

The electromagnetic catch offers a compact form factor and simple electrical operation, allowing integration with access control panels, push-button switches or timed relays. Its design minimizes moving parts compared with mechanical locks, which can reduce maintenance needs. The device enables remote-controlled release and secure holding while powered, supporting silent or low-noise operation depending on mounting and door type.

Suitable for

• Securing cabinet doors, access panels and lightweight interior doors
• Integration with access control systems and alarm panels
• Retrofit projects where non-mechanical holding is preferred
• Automatic door mechanisms and electrically controlled closures

Key specifications

• Function: Electromagnetic holding and release for doors and panels
• Installation type: Surface mount or recessed mount depending on model specifics
• Power operation: Requires external DC/AC supply or control signal (match supply to installer requirements)
• Typical use environment: Indoor applications such as furniture, cabinets and interior doors
• Operating principle: Electromagnetic attraction between catch and armature plate

How to use

Mount the electromagnetic catch in the planned position on the door frame or furniture carcass and fit the matching armature plate to the door or panel face so contact is achieved when closed. Wire the unit to the building power or control circuit following local electrical codes and the installer’s requirements, ensuring the supply type and voltage are compatible. Test the catch by energizing and de-energizing the circuit to confirm reliable holding and release and adjust plate alignment if necessary to ensure secure contact.

Usage recommendations

For reliable performance, use the electromagnetic catch in dry indoor locations and ensure correct supply voltage and polarity. Coordinate installation with the overall access control or alarm system and verify mechanical alignment of the armature plate to prevent uneven wear. Periodic inspection of mounting hardware and wiring connections is advised to maintain consistent operation.
