<p>An electromagnetic lock assembly (100) has longitudinally extending interlocking protrusions (22) and recesses (12) in the magnet (20) and magnet housing surfaces. This permits longitudinal movement of the magnet (20) within the housing (10), but prevents lifting of the magnet out of the housing. End caps (40, 50) and an electronic circuitry cover clamp the magnet longitudi- nally within the housing and provide the mounting bolt brackets. An armature (70), providing for distribution of separating for- ces, reduces bending tendencies in the armature contact plate (62) and there by increases the effective separation load bearing cap- ability of the lock assembly.</p> |
