Product SKU: EMZ8-SM
Product Overview
The Lockwood EMZ8 Electromagnetic Maglock Single 580kg Monitored 12/24VDC is a powerful electromagnetic locking solution designed for commercial access control systems. Built for single door installations, this maglock provides strong holding force and reliable fail-safe operation for controlled entry points. Its surface-mounted design makes it suitable for aluminium, steel and timber doors, while monitored status outputs provide valuable feedback to security systems. With strong holding power and flexible voltage support, the EMZ8 is a dependable choice for professional door security installations.
Why Choose the EMZ8-SM
The EMZ8-SM is designed for environments where strong magnetic locking and reliable access control integration are essential. Its high holding force helps maintain secure door closure, while dual-voltage capability allows it to operate on either 12VDC or 24VDC systems. Monitoring outputs provide confirmation of door and lock status, helping security systems detect doors left open or unlocked. With silent operation, self-aligning armature design and durable construction, this maglock provides long-term reliability for busy commercial entrances.
Key Capabilities
580kg Magnetic Holding Strength
The EMZ8 delivers strong electromagnetic holding power designed to secure commercial doors in controlled entry environments. The magnetic bond between the magnet and armature plate provides dependable locking performance suitable for high-traffic doorways.
Integrated Monitoring Functions
The monitored design includes sensors that allow the access control system to confirm door position and lock status. This provides better system awareness and helps security teams detect doors that have been forced open or left unsecured.
Fail-Safe Magnetic Lock Operation
The electromagnetic design unlocks automatically when power is removed. This fail-safe behaviour is commonly required for safety-compliant doors where emergency egress must remain possible during power outages or alarm events.
Flexible Dual-Voltage Installation
The lock can operate on either 12VDC or 24VDC power supplies, allowing installers to select the appropriate voltage during installation and integrate easily with different access control systems.
Self-Aligning Armature Plate
The armature plate is designed to pivot slightly, allowing the magnet to maintain proper contact even if the door drops or shifts slightly over time. This helps maintain consistent locking performance in real-world installations.
Key Features
-
High 580kg Holding Force: Provides strong magnetic locking designed for demanding commercial door applications where reliable security is required.
-
Dual Voltage 12VDC / 24VDC: Supports site-selectable voltage options, allowing installers to integrate the lock with different access control power supplies.
-
Low Power Consumption: The lock typically draws around 512mA at 12VDC or 256mA at 24VDC, helping maintain efficient operation in access control systems.
-
Hall Effect and Reed Switch Monitoring: Monitoring sensors confirm both magnetic bond status and door position, allowing the access control system to detect whether the door is properly secured.
-
Silent Electromagnetic Operation: The lock operates quietly without mechanical latching or buzzing, making it suitable for offices, healthcare environments and other locations where quiet operation is important.
-
Durable Surface-Mount Construction: Designed for mounting to a door frame with an armature plate on the door leaf, the lock can be installed on timber, aluminium or steel door frames commonly used in commercial buildings.

FAQs
- How does a magnetic door lock work?
A magnetic lock uses an electromagnet mounted on the door frame and an armature plate attached to the door. When power is applied, the magnet creates a strong magnetic field that holds the armature plate firmly in place. When power is removed, the magnetic bond disappears and the door can open normally. - What does fail-safe mean for a maglock?
Fail-safe means the lock releases automatically when power is removed. This design is commonly required for safety reasons because it allows occupants to exit the building during power failures or emergency situations. - What is the purpose of monitoring in a maglock?
Monitoring allows the access control system to confirm whether the lock is engaged and whether the door is closed. These signals help detect faults such as doors being forced open, doors not fully closing or locks not engaging correctly.
