OB350 Series – 350kg(800lbs) Magnetic Lock
The OUBAO OB350 Series magnetic lock is our enhanced-duty electromagnetic locking solution, delivering 350kg (800lbs) of holding force — engineered for applications demanding greater security strength while maintaining operational efficiency in dynamic commercial environments.
Built with a reinforced high-grade aluminum housing and a heavy-duty precision-machined armature plate, this lock generates substantial magnetic adhesion when energized, ensuring robust door securing across high-traffic entry points without any mechanical wear. Its fail-safe design automatically releases the door upon power failure, fully complying with international fire safety and emergency egress codes.
Globally Certified, Market-Ready — The OB350 carries UL Listing from Underwriters Laboratories for access control system units and burglary-resistant electric locking devices; bears the CE mark for full European conformity; meets FCC standards governing electromagnetic emissions in North America; and satisfies both RoHS and REACH directives, guaranteeing the absence of restricted hazardous substances and complete adherence to chemical safety protocols. A proven, compliance-assured solution for commercial deployments across diverse regulatory landscapes worldwide.
