JS-280W Electromagnetic Lock

The JS-280W Electromagnetic Lock is a robust security component engineered for professional access control systems. This device utilizes electromagnetic force to maintain a secure hold on doors, providing a reliable barrier against unauthorized entry in both residential and commercial settings. Its durable construction ensures consistent performance and longevity, making it an essential element for modern security infrastructure and controlled access management.

Advantages

This electromagnetic lock offers significant benefits for facility security, primarily through its high holding force which ensures that doors remain securely locked when the system is engaged. The design is optimized for seamless integration with various electronic access control panels, allowing for quick and efficient installation. Its lack of moving mechanical parts reduces wear and tear, resulting in a low-maintenance solution that remains operational over long periods of intensive use.

Suitable for

• Office building entrance doors
• Residential apartment complex security
• Server rooms and restricted access areas
• Commercial facility exit management

When it may not be suitable

This lock is not suitable for applications requiring fire-rated door hardware that must automatically release under specific heat conditions unless integrated with a compatible fire alarm system. It is also not intended for use on doors that require mechanical key override capabilities without additional hardware modifications.

Key specifications

• Holding force: 280 kg
• Operating voltage: 12V DC
• Material: High-grade aluminum alloy
• Application: Indoor use
• Locking mechanism: Electromagnetic

How to use

The installation of the JS-280W requires mounting the electromagnet to the door frame and the armature plate to the door leaf. Ensure that the surfaces are perfectly aligned to allow for maximum magnetic contact. Connect the device to a compatible 12V DC power supply and integrate it with your existing access control system, such as a keypad, card reader, or exit button. Once powered, the lock will engage automatically, securing the door until the access control system sends a signal to release the magnetic hold.

What to consider before purchase

• Verify that your door frame is strong enough to support the mounting of the magnet.
• Ensure your power supply unit provides a stable 12V DC output.
• Check if your access control system requires a normally closed or normally open configuration.

Usage recommendations

For optimal security and longevity, ensure the armature plate is installed with a slight amount of flexibility to allow for perfect alignment with the magnet face. Regularly clean the contact surfaces to prevent dust accumulation, which can weaken the holding force.
