Product Description
The ZKTeco LM-2805 Electromagnetic Lock is a high-performance magnetic door lock designed for secure and reliable access control systems. It operates using electromagnetism, where power creates a strong magnetic force to keep the door locked, and releases instantly when power is cut (fail-safe operation).
With a strong holding force of up to 280kg (≈600 lbs), it ensures secure locking for glass, wooden, and metal doors in offices and commercial environments.
The key advantage of the LM-2805 over standard models (like LM-2802) is its built-in door status signal output (NO/COM/NC), which allows integration with advanced access control systems for monitoring door status in real time.
Constructed with durable materials and designed for continuous operation, this lock is widely used with fingerprint devices, RFID readers, and video intercom systems for complete security solutions.
