Lockwood EMZ8-SN Single Electromagnetic Lock — 12/24 VDC, Fail-Safe
The EMZ8-SN is a single, surface-mounted electromagnetic lock from the Lockwood Padde Z-Series. It is a fail-safe device (unlocks when power is removed) with dual-voltage 12/24 VDC selection, smart electronics for instantaneous release, and a self-aligning armature that pivots to accommodate door drop. Designed for fast install on timber, aluminium, steel and glass doors (with the correct brackets). This SN variant is non-monitored; if status outputs are required, select the EMZ8-SM monitored version.

Additional Information
The Lockwood Padde Single Series electromagnetic locks cover a wide range of applications, with holding forces from approximately 200 kg up to 450 kg across the Z4 and Z8 models. They are suitable where the door may need to be supervised for position and, on monitored models, for whether the magnet is bonded. From cupboard doors through to high-use commercial swing doors, Z-Series magnets offer a simple, robust and reliable fail-safe solution.
Installation is straightforward: the range supports timber, aluminium and steel constructions, and there are dedicated bracket options for glass door applications. The self-aligning armature pivots to accommodate door drop, reducing call-backs after settling or seasonal movement. Smart electronics ensure instantaneous release with zero residual magnetism, so the door opens cleanly on command without drag.
Specification Statement: The Single Series electromagnetic lock shall be housed in an aluminium case with heavy-duty electromagnet and operate in fail-safe mode (power to lock). The lock shall incorporate smart electronics that provide instantaneous release with zero residual magnetism. A self-aligning armature plate shall compensate for door drop. For installations requiring status signals, select a monitored variant that provides reed switch door position monitoring and hall/bond monitoring of the lock status. Where life-safety or continuity of security is essential, provide a secondary mechanical lock or battery backup.
