YLI YM-350ND(LED)-DS 350kg Double Door Magnetic Lock with LED & Bond Sensor(800Lbs x2)
350kg x 2 (800Lbs x 2) holding force, DC12V(Default); DC24V(Adjustable), 12V/500mA(±10%)x2 ; 24V/250mA(±10%)x2, Anodized hard plating (500-hour salt spray test report) casing, fail-safe operation.
The YLI YM-350ND(LED)-DS delivers 350kg x 2 (800Lbs x 2) of static holding force designed for commercial access control. Built with high-strength anodized aluminum casing, zero residual magnetism, and 240-hour anti-corrosion salt spray certification.
Product Overview
YM-350ND(LED)-DS Double door magnetic lock is designed for wooden door, metal door, glass door and fireproof door. There are both lock status signal (NO/NC/COM) output contacts and door status signal (NO/NC/COM) output contacts. The lock body is equipped with a large LED light. The green light indicates unlocking, and the red light indicates locking. YLl magnetic lock cores are produced with robotic laser welding technology, providing 2 to 3 times stronger impact resistance and torsional resistance than conventional production processes. The surface is treated with the internationally leading electroplating process and the lock itself has passed the 240 hour salt spray test in the national laboratory, achieving excellent performance of anti-oxidation, anti-rust and anti-corrosion.Our company offers a complete range of brackets for different locks.
Why Buy This Product
Certified 350kg x 2 (800Lbs x 2) Holding Force
Rigorously tested to resist up to 350kg x 2 (800Lbs x 2) of direct pull force, providing impenetrable magnetic locking against forced intrusions.
Robotic Laser Welded Core
Built with robotic laser welding technology, offering 2 to 3 times superior impact resistance and torsional rigidity compared to standard castings.
Instant 0.5s Demagnetization
Integrated mechanical push-off pin and precision demagnetizing coil completely eliminate residual magnetism, preventing sticky door release.
240-Hour Salt Spray Protection
Multi-layer electroplating and anodized shell exceed 240-hour salt spray corrosion tests, guaranteeing rust-free operation for years.
Best for These Applications
Corporate Double Glass Entrances
Securing twin-leaf main entrance glass, wooden, or metal doors in high-traffic offices.
Life Safety Emergency Exits
Fail-safe compliance ensuring instantaneous door release upon building fire alarm activation.
Financial Institutions & Vaults
Heavy-duty dual magnetic retention for bank branch entrances, cash rooms, and record archives.
Hospitals & Healthcare Facilities
Controlled access for hospital double swing corridor doors and restricted surgical wings.
Key Advantages
- Zero Residual Magnetism Mechanism:An anti-residual magnetism kick-off pin and precision demagnetizing circuit discharge residual flux within 0.5s when power is cut, preventing door drag.
- UL94 V-0 Flame-Retardant Encapsulation:Electromagnet coils are encapsulated with American UL-certified fireproof resin, sealing out humidity, dust, and electrical breakdown risks.
- Integrated MOV Surge Suppression:Built-in metal-oxide varistor absorbs back-EMF inductive voltage spikes, protecting sensitive access controllers and power supply relays.
- Universal Bracket Hardware Compatibility:Engineered for seamless mounting with YLI MBK-series L-brackets, ZL-brackets for in-swing doors, and U-brackets for frameless glass doors.
