YLI YM-350NTD(LED) 350kg Double Door Magnetic Lock with LED, Signal & Time Delay(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-350NTD(LED) 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-350NTD(LED) Double door magnetic lock is designed for wooden door, metaäºdoor, glass door and fireproof door. lt has an adjustable time delay function of 0/3/6/9 seconds. There is a set of lock status signal (NO/NC/COM) output contacts, which provides real-time feedback for the access control system. 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.
