YLI YM-2400SL Concealed Shear Lock (1200kg / 2600Lbs)
1200kg (2600Lbs) shear holding force, 12VDC / 24VDC, Start: 12V/850mA, 24V/430mA; Holding: 12V/220mA, 24V/110mA, Time delay 0/5/10/15 seconds, Door status (NO/NC/COM), Lock status (NO/NC/COM), Concealed mortise mount.
The YLI YM-2400SL is a concealed electromagnetic shear lock delivering 1200kg (2600Lbs) of holding force. Engineered for double-swing doors (180° swing), frameless glass doors, and executive commercial entrances where invisible hardware and ultra-high shear resistance are paramount.
Product Overview
YM-2400SL is an electromagnetic shear lock utilizing electromagnetic attraction and dual hardened alloy shear tabs to resist up to 1200kg (2600Lbs) horizontal shear force. Designed for double-swing doors.
Why Buy This Product
1200kg (2600Lbs) Impenetrable Shear Strength
Combines intense magnetic attraction with interlocking alloy shear lugs, resisting over 1.2 metric tons of horizontal forced entry.
Engineered for Double-Action 180° Swing Doors
Unlike conventional surface magnetic locks, shear locks mount flush inside the frame, allowing doors to swing freely in both inward and outward directions.
Completely Concealed Architectural Finish
Mortise installation hides all locking components within the door header and leaf, preserving pristine aesthetics for glass and executive entrance doors.
Continuous Life Safety Fail-Safe Operation
Instantly releases upon power cut or emergency fire signal, ensuring fully compliant, unhindered emergency egress.
Best for These Applications
Double-Swing Commercial Glass Doors
Securing corporate office entrances, glass pivot doors, and bank lobbies where doors swing both inward and outward.
Executive Office Suites & Boardrooms
Architectural entrances demanding concealed hardware without unsightly brackets or exposed surface magnets.
Fire Emergency Exit Corridors
High-traffic corridor doors requiring automatic fail-safe release upon fire alarm trigger and uninhibited two-way flow.
High-Security Access Control Portals
Interlocking airlocks and secure data access mantrap doors requiring independent door and lock status monitoring.
Key Advantages
- Dual Shear-Lug Mechanical Lockup:Precision hardened alloy shear tabs drop into corresponding recesses upon magnetic attraction, converting pure magnetic flux into immense physical shear resistance.
- Dual Independent Status Relays (NO/NC/COM):Provides discrete dry contacts for both door closure status and actual physical lock engagement, preventing false secure indications.
- Multi-Stage Auto-Relock Delay (0/5/10/15s):Configurable on-board timer gives pedestrians ample time to push through heavy swinging doors before the shear mechanism engages.
- Overvoltage & Back-EMF Surge Suppression:Built-in metal-oxide varistor circuit absorbs inductive flyback voltage spikes, safeguarding access control boards and power supplies.
