　　Anti-EMI Magnetic Connector: Engineered for High-Speed Data Transmission Systems

　　High-speed data transmission systems—from data center servers to industrial Ethernet networks—operate at gigabit rates where even minor signal degradation or electromagnetic interference (EMI) can cause packet loss, latency spikes, or system failures. Our anti-EMI magnetic connector is purpose-built to address these challenges, combining secure magnetic coupling with advanced shielding to maintain signal integrity in high-noise environments, making it ideal for 1Gbps to 10Gbps+ data transmission scenarios.

　　Core Performance for High-Speed Data Integrity

　　Gigabit-Level Transmission Capability

　　Bandwidth Support: Designed to handle data rates up to 10Gbps (compliant with IEEE 802.3 standards), the connector features precision-machined signal pins with controlled impedance (50Ω ±10% for differential pairs), ensuring minimal signal reflection and insertion loss (≤1.5dB at 10GHz).

　　Signal Integrity Optimization: Internal signal paths are engineered with short, matched lengths to reduce skew (≤5ps), while gold-plated contacts (3μm thickness) minimize contact resistance (≤5mΩ) and ensure stable electrical performance over thousands of mating cycles—critical for maintaining bit error rates (BER) below 1×10⁻¹² in high-speed links.

　　Advanced Anti-EMI Shielding

　　Multi-Layer Shielding: Integrates a dual-layer shield—inner Permalloy (nickel-iron alloy) for low-frequency EMI absorption (100kHz~1GHz) and outer tin-plated copper for high-frequency reflection (1GHz~10GHz)—achieving an EMI suppression effectiveness of ≥40dB across the entire frequency spectrum. This blocks interference from nearby power cables, motors, and radio frequency (RF) equipment.

　　EMC-Compliant Design: Signal and power paths are physically separated with a high-dielectric insulator (relative permittivity ≥3.0), reducing crosstalk between pairs (near-end crosstalk ≤-30dB at 10Gbps) and meeting FCC Part 15 and CE EMC standards for industrial and commercial environments.

　　Magnetic Coupling Advantages for High-Speed Systems

　　Secure and Efficient Connection

　　Magnetic Alignment: High-strength NdFeB magnets (1500Gs surface field) enable blind mating with ±0.5mm positional tolerance, simplifying installation in densely packed enclosures (e.g., server racks, industrial control panels) where visual alignment is difficult. The 8N adsorption force ensures stable contact even under vibration (10Hz~2000Hz, 10g acceleration per IEC 60068-2-6).

　　Tool-Free Operation: Magnetic coupling eliminates the need for screws or latches, reducing mating time by 70% compared to traditional connectors. This is critical for rapid maintenance or module hot-swapping in data centers, where downtime must be minimized.

　　Durability for Continuous Operation

　　Robust Construction: Housing is made from UL 94 V-0 rated PBT with glass fiber reinforcement, resisting impact, chemicals, and UV exposure. The connector withstands 10,000+ mating cycles without performance degradation—far exceeding the lifespan of typical plug-in connectors in high-usage environments.

　　Environmental Resilience: IP65-rated sealing protects against dust and water spray, making it suitable for industrial Ethernet systems in factory floors or outdoor telecom cabinets. It operates reliably across -40°C to 105°C, ensuring performance stability in temperature-fluctuating environments.

　　Key Applications in High-Speed Data Systems

　　Data Center and Server Infrastructure

　　Connects blade servers to backplane switches or storage arrays, supporting 10Gbps Ethernet or InfiniBand links. The EMI shielding prevents interference between densely packed server modules, reducing packet loss by ≥95% compared to unshielded connectors.

　　Industrial Ethernet Networks

　　Enables high-speed communication in PROFINET, EtherCAT, or Modbus TCP/IP networks, linking PLCs to vision systems, robots, and HMIs. The magnetic design allows quick disconnection during line reconfigurations, while EMI resistance ensures reliable 1Gbps+ data flow in factories with heavy machinery.

　　Test and Measurement Equipment

　　Serves as a high-speed interface in oscilloscopes, signal analyzers, or data acquisition systems, where precise signal transmission (up to 10Gbps) is critical for accurate measurements. The low insertion loss and crosstalk ensure minimal distortion of high-frequency signals.

　　Compliance and Reliability

　　Industry Certifications: Complies with CE, FCC, RoHS, and IEC 61076-3-124 (industrial high-speed connectors), meeting global standards for data transmission and environmental safety.

　　Reliability Testing: Undergoes 1000-hour high-temperature aging (105°C) with full data load, 5000 mating cycles, and 1000 thermal shocks (-40°C to 105°C), with signal integrity parameters remaining within specification—guaranteeing stable operation for 5+ years in 24/7 systems.
