SDC 1561 HTCM Hi Shear® Magnetic Door Locks

The SDC 1561 HTCM Hi Shear® is a totally concealed, high security, failsafe locking mechanism with superior appearance. The patented Hi/Shear® electromagnetic lock design incorporates a “floating” armature assembly and special alloy steel locking “tabs” on both the lock and armature assemblies, that may be adjusted both vertically and laterally to compensate for wide door gaps and warped or misaligned doors. Hi/Shear® magnetic locks are ideal for use on commercial grade hollow metal and wood doors and metal frames and Herculite doors with top rails.


Door Static and Alignment Sensor: The door static sensor ensures that the door is at rest and aligned, before the magnet is permitted to energize, eliminating potential for lock misalignment.

Lateral Alignment Adjustment: Lateral adjustment of shear tabs to compensate for warped or misaligned doors, permitting accurate locking.

Vertical Alignment Adjustment: Vertical adjustment of the armature compensates for wide door gaps

Floating” Assembly: A unique “floating” action makes for easier armature lift when the magnet is energized and provides the ability to overcome wide door gaps.

Holding Force: 2000 lbs of holding force without current inrush or high operating temperature normally associated with shear locks.

Alloy Steel Shear “Tabs” on Lock and Armature: Alloy shear tabs are used on both the lock and the armature to ensure continued high holding force. There is no profiling of the soft armature steel that may be prone to wear and reduced holding force.

Advanced Electronic Circuitry: Advanced electronic circuitry that incorporates door static, positioning and timed relock sensor and automatic voltage sensing for 12/24VDC input.

Quieter Operation: Noise dampeners greatly reduce the noise associated with locking and unlocking of other shear locks on the market.
