　　Anti-Electromagnetic Interference Magnetic Connector (10A Max Current): Reliable Connection in Complex Environments

　　In the era of intelligent equipment, stable power supply and signal transmission in complex electromagnetic environments have become critical challenges. Our anti-electromagnetic interference (EMI) magnetic connector, with a maximum current carrying capacity of 10A, combines the convenience of magnetic adsorption with the reliability of anti-interference design, becoming an ideal choice for industrial control, medical equipment, and consumer electronics.

　　Core Performance: Balancing High Current and Anti-Interference

　　10A High-Current Transmission Capacity

　　Power Supply Stability: The connector adopts a multi-pin parallel design, with each pin made of high-conductivity copper alloy (conductivity ≥98% IACS). The contact resistance is ≤10mΩ, ensuring stable transmission of 10A current (sustained) and 15A peak current, meeting the power demand of medium-power devices such as industrial sensors and medical monitors.

　　Thermal Management Optimization: The housing is made of high-temperature resistant PBT material (operating temperature -40°C~105°C), and the internal contact area is enlarged by 30% compared with traditional connectors, effectively reducing heat accumulation. Even when transmitting 10A current continuously for 24 hours, the surface temperature rise is ≤20°C, avoiding thermal aging of surrounding components.

　　Multi-Layer Anti-EMI Design

　　Magnetic Shielding Layer: A nickel-iron alloy (Permalloy) shielding layer is built into the connector, which can absorb and attenuate electromagnetic waves in the 100kHz~1GHz frequency band, with an interference suppression effect of ≥30dB, ensuring that signal transmission is not affected by surrounding motors, inverters, and other equipment.

　　Structural Optimization: The contact pins are arranged in a staggered manner, and the signal pins and power pins are separated by an insulating barrier (dielectric strength ≥500V AC), reducing crosstalk between signals and power, and ensuring that the signal transmission rate reaches 1Gbps without packet loss.

　　Magnetic Adsorption Advantage: The built-in high-performance NdFeB magnet (surface magnetic field strength 2000Gs) realizes fast docking (docking time ≤0.5s), and the adsorption force is 8N, which is not easy to fall off under vibration, while avoiding the electromagnetic interference caused by mechanical contact sparks.

　　Structural Design: Durability and Convenience

　　Robust and Compact Structure

　　Dimension Control: The overall size is as compact as 20mm×15mm×8mm (length×width×height), which can be easily integrated into small devices such as portable medical instruments and smart home controllers, saving installation space.

　　Mechanical Strength: After 10,000 times of plugging and unplugging tests, the contact resistance change rate is ≤15%, and the housing has no cracks or deformation, meeting the long-term use needs of industrial environments.

　　Safety and Environmental Adaptability

　　Safety Certifications: Compliant with UL 94 V-0 flame retardant standard, passed RoHS and REACH environmental protection tests, free of 10 substances of very high concern (SVHCs), meeting the import requirements of EU, North America, and other markets.

　　Environmental Resistance: It has IP65 dustproof and waterproof performance. After being immersed in 1m deep water for 30 minutes, it can still work normally, adapting to harsh environments such as humid workshops and outdoor equipment.

　　Typical Application Scenarios

　　Industrial Automation

　　Used for the connection between robotic arms and end effectors, it can transmit 10A power and control signals at the same time. The anti-interference design ensures stable operation in the electromagnetic environment of factories, reducing the failure rate of equipment by 40%.

　　Medical Equipment

　　Applied to portable ventilators and monitors, the magnetic adsorption design avoids the risk of accidental disconnection caused by collision, and the anti-EMI performance ensures the accuracy of physiological signal transmission (such as ECG, blood pressure) to ensure the reliability of medical monitoring.

　　Consumer Electronics

　　As the charging and data transmission interface of high-power wireless charging pads, it supports 10A fast charging while resisting the electromagnetic interference of mobile phone signals, ensuring charging efficiency ≥90%.
