YLI YML-850B European Electric Mechanical Lock with Cylinder
1000 Lbs strike force, 12~24VDC/AC, ≤300mA, 275Lx25Wx51.9H, all-metal structure, 500,000 cycles certified.
The YLI YML-850B is a heavy-duty European electromechanical mortise lock engineered for high-security one-way and two-way swing doors. Features all-metal transmission linkages, 1000 Lbs strike force resistance, field-reversible NO/NC operation, and European profile cylinder manual mechanical key override.
Product Overview
YML-650B is our electromechanical lock,which is suitable for one-way open and two-way open doors,including wooden door,metal door,framed glass door etc.Stainless steel housing,unique design for safety requirement,switches to working mode by manual control.Bolt bears up to 1000lbs strike,coming with European type cylinder.In working mode,itâs under control by electricity while by manual control if under emergency.All linkages are metal structure.Work normally under the temperature between -40°Cand 60°C.Pass 500000 times test.Outstanding performance,prior choice for project.
Why Buy This Product
1000 Lbs Impact Strike Resistance
Solid stainless steel latch and deadbolt mechanism withstand severe battering and forced intrusion attempts up to 1000 Lbs.
Dual Electric & Manual Egress
Combines fast electronic card/biometric release with traditional manual key cylinder operation for complete life-safety redundancy.
Extreme -40°C to +60°C Climate Tolerance
Engineered with specialized aerospace lubricants and all-metal gearing to prevent cold-seizing or heat expansion failure.
Field-Reversible Fail Mode
Easily switches between Fail-Secure (power to unlock) and Fail-Safe (power to lock) directly on the lock body without replacing parts.
Best for These Applications
Heavy Commercial & Industrial Doors
High-traffic solid timber, steel, and hollow metal doors in factories, warehouses, and corporate facilities.
Bank Branches & Cash Offices
Financial institution secure perimeter doors requiring both electrified access control and manual supervisory key control.
Multi-Unit Residential Perimeter Entrances
Apartment block main entrance gates requiring durable electromechanical latching with intercom release.
Fire Emergency Stairwell Portals
Stairway fire doors requiring positive latching against fire drafts while maintaining fail-safe release.
Key Advantages
- All-Metal Precision Transmission:Zero plastic or composite internal components; all linkages are machined from hardened steel and brass for maximum torque.
- Continuous 500,000 Cycle Durability:Passed intensive national laboratory durability stress testing exceeding 500,000 mechanical operations.
- Independent Dual Signal Monitoring:Discrete dry contacts provide real-time status indication for both door leaf position and physical deadbolt engagement.
- Standard European Mortise Pocket:Dimensions conform to European DIN architectural standards, facilitating straightforward retrofitting into existing doors.
