GF3000 and 280+ Series Electromagnetic Shear Locks The Locknetics GF3000 Series Shear Locks pioneered a totally new concept in electromagnetic locking systems. When power is applied to the magnet, it drops to meet the armature through a combination of gravity force and magnetism. Both the magnet and the armature “float” on retraction springs, allowing each to jump to engage each other. Interlocking tabs on the magnet housing engage with grooves on the armature to provide holding force in excess of 3000 pounds. Surface-mounted models are available. The 280+ Series Shear Locks employs a special "PowerPlus" module which provides a surge of power to "boost" the magnetic field strength for a short time, thereby causing the armature to engage with the magnet. The 280+ Series is designed for applications where small physical size is desired. Holding force is 2700 pounds. Surface-mounted models are available. Both the GF3000 Series and the 280+ Series include automatic time delay on relock, automatic voltage selection, and automatic relock door position switch (ARS). Each offers a magnetic bond sensor option, which provides lock status. Both Series require the use of conventional, filtered, regulated power supply and draw 0.9A @ 12VDC or 0.45A @ 24VDC. Models are available for multiple applications including metal door and frame,
glass door with top rail and metal frame, wood door and frame, top rail installations,
and bottom rail installations. Locknetics |
