Import A280 — Buy in wholesale FOB from Supplier in China

The A280 is an electromagnetic lock designed for access control integration in commercial and industrial security applications, manufactured by Ocean International Technology Co., Ltd in Shenzhen, China. The lock body measures 250 mm by 48 mm by 27 mm, with an armature plate of 180 mm by 38 mm by 11 mm, dimensions that indicate a standard single-door surface-mount installation rather than a mortise or concealed application. It operates at DC 12V with a current draw of 500 mA, delivering a holding force of 280 kg (approximately 617 lb), which suits wooden, metal, and glass doors in medium-security environments. The supplier specifies a zinc alloy housing, electromagnetic coil, and steel armature as the core material set, a construction typical for fail-safe magnetic locks in this force category.

The A280 incorporates an LED status indicator, monitoring sensor, and adjustable timer function, features that distinguish it from basic magnetic locks and enable integration with building management systems and alarm panels. The LED provides visual confirmation of lock state, the monitoring sensor detects door position or lock status for feedback loops, and the timer can delay release or relock sequences to coordinate with access control readers or egress devices. Standard industry practice for 280 kg-class magnetic locks typically includes a holding force tolerance of plus or minus 10 percent, operating temperature ranges of -10 to 55 degrees Celsius, and surge protection on the coil circuit. The steel armature and zinc alloy housing combination offers corrosion resistance for indoor installations, though salt spray ratings and IP ingress protection levels are not stated in the source data.

This electromagnetic lock serves security system integrators, access control distributors, and commercial building contractors importing hardware for installation in offices, retail premises, healthcare facilities, and educational institutions. The DC 12V/500 mA power requirement aligns with standard access control power supplies, though buyers should confirm inrush current during activation and whether the coil includes thermal protection against sustained energisation. The supplier's profile indicates suitability for glass doors and fire exit doors, the latter requiring careful coordination with fire alarm systems to ensure automatic release upon fire detection. No MOQ, packaging specifications, or lead times are stated, so buyers must request this information directly from Ocean International Technology to plan project timelines and inventory requirements.

Ocean International Technology Co., Ltd is located in Guorun Industrial Park, Minzhi Street, Longhua District, Shenzhen 518131, China, operating from Building 2, unit B3. The supplier holds a harbor trust tier, which indicates basic listing verification without advanced assurance or sustained transaction history on the platform. The response rate and average response hours both show zero values, meaning buyers cannot rely on platform-measured communication metrics and must establish responsiveness through direct enquiry. The Longhua District location places the company within Shenzhen's electronics manufacturing corridor, though this geographic proximity to component suppliers does not indicate production scale or in-house manufacturing capability.

The available profile does not state year of establishment, registered capital, employee count, factory floor area, annual turnover, or specific client references. The company's product focus centres on access control hardware, with this A280 electromagnetic lock positioned for security integrators and building automation markets. No ISO 9001, ISO 14001, or specific product certifications (CE, UL, FCC) are confirmed in the source data. The industrial park address suggests a commercial or light industrial facility rather than a heavy manufacturing campus, though this cannot be confirmed without site inspection. Buyers should request business registration documents, factory audit reports, and existing customer references before committing to volume orders.
