OB50 Series – Magnetic Lock for Cabinet
The OUBAO OB50 Series magnetic lock is our miniature electromagnetic locking solution, delivering low weight of holding force — purpose-engineered for cabinet, display case, and enclosed fixture applications where discreet security and compact form factor are paramount.
Built with a miniaturized aluminum alloy housing and a precision-machined micro armature plate, this lock generates secure magnetic adhesion when energized, ensuring reliable protection for valuable contents without any mechanical wear or audible operation. Its fail-safe design automatically releases upon power failure, permitting immediate access in emergency situations. With an ultra-compact profile and featherlight construction, the OB50 installs seamlessly into narrow door frames, glass display cases, wooden cabinets, and retail fixtures where conventional locks are impractical. Power consumption is minimal at merely 100mA @ 12VDC, enabling continuous operation without thermal burden — ideal for museums, retail showrooms, jewelry counters, server racks, and pharmaceutical storage.
Internationally Certified for Diverse Deployment — The OB50 carries CE marking for European conformity, complies with FCC electromagnetic standards for North American integration, and satisfies RoHS and REACH environmental directives, ensuring freedom from hazardous substances and full chemical safety compliance. A discreet, regulation-ready security solution for compact enclosures across global commercial and residential environments.
