2000kg (4400Lbs) static strength, fail-secure, DC12V(DC24V need order), Start 5.0A, Standby 0.6A, Lock signal(NO/NC/COM), 304 stainless steel bolt.
The YLI YB-900 is an intelligent commercial electric drop bolt delivering 2000kg (4400Lbs) static shear resistance. Built with a solid 304 stainless steel latch pin, Fail-Secure (power to unlock, power off to lock) security mode, and tested to withstand over 500,000 continuous duty cycles.
Product Overview
YB-900 is an enhanced all-metal construction electric bolt.with European-type cylinder and key function,which has achieve the purpose of double use of electric control and manual control functions. The 304 stainless steel bolt , produced by CNC Lathe seiko, can withstand 2000kg holding force.The Professional and durable solenoid valve is qualified after 1 million times of ageing test. Rain-proof design satisfy the installation request of indoor and outdoor.
Why Buy This Product
Certified 2000kg (4400Lbs) Shear Resistance
Rigid mechanical construction tested to withstand up to 2000kg (4400Lbs) of lateral shear force against violent forced entry attempts.
500,000 Cycles Proven Durability
Equipped with custom commercial-grade electromagnetic solenoids and low-friction bronze bushings rated for over 500,000 continuous operations.
Ultra-Low Operating Temperature Design
Advanced electronic current-stepping cuts power consumption by up to 80% during standby, preventing thermal buildup and door frame warping.
Full Access Control Ecosystem Compatibility
Provides standardized dry contact outputs (NO/NC/COM) that integrate effortlessly with access controllers, alarms, and fire release systems.
Best for These Applications
Commercial Frame & Frameless Glass Doors
Tailored for Steel gates, Heavy door in corporate headquarters, retail fronts, and executive boardrooms.
High-Security IT & Server Rooms
Restricting unauthorized access to telecommunication closets and data centers requiring monitored electric bolt locking.
Double-Swing Corridor Entrances
180-degree pivoting glass doors where conventional magnetic locks cannot provide concealed deadlocking.
Emergency & Fire Exit Portals
Life-safety egress doors requiring instant unlocking upon emergency power disruption or fire panel activation.
Key Advantages
- Solid 304 Stainless Steel Latch Pin:Latches into the strike plate with a 16mm diameter hardened 304 stainless steel pin, resisting hacksaw cutting and heavy crowbar leverage.
- Intelligent Optical / Magnetic Sensor Sensing:Accurate door position detection guarantees the bolt only extends when the door is perfectly closed, preventing strike plate damage.
- Selectable Auto-Relocking Time Delays:Configurable delay jumpers (0, 3, 6, 9 seconds) prevent premature latch throwing while pedestrians walk through the doorway.
- Integrated MOV Overvoltage Protection:Absorbs inductive voltage kickback from the solenoid during power off, protecting access controller relays from electrical degradation.
