YLI YB-241DMD(LED) Motor Driven High Security Electric Lock
2000kg (4400Lbs) holding force, Motor-Driven Mute, 12~28VDC, ≤500mA, IP65, Dual Status Sensors, 304 Stainless Steel Bolt.
The YLI YB-241DMD(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
Motor driven mute electric bolt,the bolt is controlled by motor drive to realize lock and unlock. The driving force of the motor is very strong,the bolt can be pushed out by the powerful thrust of the motor to align the door when the door is deformed or misaligned. The parts are made of lightweight materials, work more smoothly, less resistance, can achieve mute when lock and unlock.The PCB is equipped with an electronic protection device to realize the precise control of locking and unlocking. In addition,compared with the traditional electric bolt which uses electromagnet to lock, which is low power consumption, energy saving and environmental protection.
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.
