With the 2.5mm² wire capacity of the SM connector built into SM’s smart home wiring solution and the push-pull locking mechanism, 58% of the installation time for the millet whole house smart system is saved. For 40℃/95% RH accelerated aging test, rate of change in contact resistance of silver-plated contact (0.2μm thickness) is less than 1.5%, ±0.5N accuracy maintained in insertion and withdrawal force, 10 years guaranteed maintenance-free. When a smart lighting company switched to SM connectors, the wiring error rate decreased from 3.7% to 0.05%, labor cost was saved $0.35/node, and the overall cost of wiring for the project decreased by 19%.
In the field of application for generating new energy power, SM connector achieves 30 minutes quick plug on the photovoltaic system’s 1500V solar power supply and contact point temperature rise of ΔT≤25K@100A, and improves heat dissipation efficiency by 14% compared to MC4 connector. In its two-contact design, failure MTBF (mean time to failure) is increased to 120,000 hours, reducing operating costs by $0.025/W/year. State Grid’s actual data show that the group inverter with SM connector lowers the failure rate of the group inverter to 0.07 times/year from 0.8 times/year, saves 1.7% of the power generation, and raises the annual income of a single 100MW power plant by over 3.6 million yuan.
Compared with rail transit usage, resistance to 50G shock vibration in the electric cabinet of 600 km/h operational maglev train can be guaranteed for SM connector, and bit error rate of signal transmission is regulated under 1×10⁻¹². Its fire rating is also up to UL94 V-0, the smoke toxicity index 63% lower than the EN45545-2 standard, and it passed the 3-hour 860℃ combustion test successfully. Shanghai-kunming high-speed rail project test, SM connector at 3800m altitude, -40℃ severe environment, contact resistance fluctuation ≤0.3mΩ, 5 times more stable than the European standard EN50155 specified value.
In the miniaturization technology, the ultra-thin thickness of the SM connector is only 3.5mm, replacing the traditional ZIF connector of the OPPO folding screen mobile phone FPC cable, and the wiring space of the rotating shaft is reduced by 41%. Its self-cleaning coating technology can make the contact contamination impedance below 5mΩ, maintain signal integrity after 200,000 times bending test, and reduce the miscontact rate from 0.15% to 0.003%. After the DJI Mavic 3 UAV uses the SM connector, the weight of the flight control harness is reduced by 1.2 grams and the endurance is improved by 2.3 minutes. The chance of signal interference in the vibration environment is reduced to 0.0005 times/hour.
According to the China Electronic Components Industry Association 2024 report, the domestic industrial connector market share for SM connectors is 39.7%, exported to 68 countries, and localization replacement rate for photovoltaic, new energy vehicles and other applications reaches above 82%. TE Connectivity comparison tests reveal that the performance degradation rate of SM connectors in salt spray, wet and heat composite environment is 42% lower than that of its comparable products while the price is only 65%. After SM connector was used in the AVIC C919 large aircraft program, the weight of avionics system cables was reduced by 18 kg, wiring cycle time was reduced by 37%, and vibration environment contact resistance deviation was below 0.8%, and this provided strong technical support to the independence of the country’s large aircraft supply chain.
