YLI YB-1500MD(LED) Motor Driven High Security Electric Lock
2000kg (4400Lbs) holding force, Motor-Driven Mute, 12ï½28VDC, ≤500mA, IP65, Dual Status Sensors, 304 Stainless Steel Bolt.
The YLI YB-1500MD(LED) is an advanced motor-driven mute electric lock engineered for ultra-quiet operation, 2000kg (4400Lbs) holding force, and high-security access control. Featuring motorized bolt extension and retraction rather than solenoid spring action, eliminating mechanical latch slamming and providing certified IP65 weatherproofing.
Product Overview
The motor driven mute electric bolt is locked and unlocked by the activity of the bolt which is driven by the stepping motor. The stepping motor has great strength, the powerful thrust of the stepping motor can be used to push the bolt to align the door to achieve the purpose of locking when the door is deformed or skewed. All parts are made of metal material, the mechanical structure of inserting and resetting has been treated with noise reduction. The two Hall components on the PCB board can accurately locate and control the stretch out and draw back of the bolt, so that unlocking and locking can be muted. Compared with the traditional electric bolt using solenoid valve structure, when the product enters the locking and unlocking state, there is no need to power the motor continuously, low energy consumption and environmental protection. The lock can also be customized with an emergency unlocking module (external), it can be unlocked automatically in case of sudden power failure.
Why Buy This Product
Whisper-Quiet Motorized Actuation
Replaces loud solenoid clatter with a precision geared stepper motor, delivering virtually silent locking ideal for corporate offices and luxury residences.
Massive 2000kg (4400Lbs) Holding Force
Heavy-duty internal gearing and solid stainless steel construction resist up to 2000kg (4400Lbs) of horizontal and vertical forced entry force.
Certified IP65 Weatherproof Rating
Fully sealed epoxy encapsulation and gasketed housing achieve IP65 protection against rain, wash-down spray, and atmospheric dust.
Wide Voltage Tolerance 12-24VDC
Wide-band input regulation prevents motor stalls during line voltage drops or extended cable runs in commercial developments.
Best for These Applications
Executive Offices & Quiet Zones
Boardrooms, law offices, and luxury clinics where standard solenoid bolt slamming sounds cause unwanted disruption.
Luxury Residential Entrances
Apartment main entrance doors and high-end smart homes requiring elegant, quiet motorized latching.
Elevator Car & Shaft Interlocks
Elevator landing doors, lift cars, and hoistway barriers demanding heavy-duty holding force and dual position monitoring.
Outdoor & Perimeter Security Gates
High-traffic exterior gates requiring IP65 ingress protection and resistance to harsh weather conditions.
Key Advantages
- Motor-Driven Controlled Latch Motion:Unlike spring-loaded solenoids that can jam under door pressure, the internal motor drives the bolt home smoothly with consistent mechanical torque.
- Zero Heat Generation on Standby:Once the motor drives the bolt into the locked position, power drops to minimal holding current, eliminating heating and thermal expansion.
- Dual Independent Status Relays (NO/NC/COM):Dedicated dry contacts provide discrete status for both door closure alignment and physical deadbolt engagement.
- Bi-Directional Door Compatibility:Engineered with symmetric strikes and multi-position sensors to support both left-hand and right-hand swinging doors.
