ZKTeco AL135 NO Electromagnetic lock

The ZKTeco AL135 NO is a compact electromagnetic lock designed for use in access control systems on light to medium-duty doors, including office partitions, interior doors, cabinets, and small entrance points. The lock operates on the principle of electromagnetism: when electric current passes through the silicon steel plate, it generates a strong magnetic attraction that securely holds the door closed, while cutting power instantly releases the attraction, allowing the door to open freely.

With a holding force of approximately 135kg, the AL135 NO is well suited for doors with moderate load requirements, offering an efficient alternative to the heavier-duty models in the AL series. It operates on 12V DC power and includes an NO (normally open) signal output, allowing integration with access control panels for real-time door status monitoring.

The AL135 NO's housing is built from quality, corrosion-resistant materials, ensuring long service life even under heavy daily use, with no residual magnetism or mechanical wear over time. Its compact size and straightforward mounting make it easy to install in both new construction and retrofit projects. The AL135 NO is a dependable, cost-effective choice for offices, retail stores, educational institutions, and other spaces requiring a basic level of electromagnetic door locking.
