The SRS(4100) Relay breaks away from the conventional logic of "simply stacking parameters" and focuses on the core needs of low-power scenarios to create differentiated value: 5% ultra-low release voltage combined with ≤50mΩ ultra-low contact resistance forms a dual advantage of "precise control + low loss" - the former allows for zero-delay and smooth circuit start-stop response, perfectly adapting to scenarios requiring fine control such as micro smart home appliances and precision sensing modules; the latter significantly reduces power transmission loss, and with 0.2W/0.36W dual-level low-power coils, it helps terminal products achieve energy-saving upgrades and solves the pain point of "difficulty in balancing control precision and energy consumption" in low-power devices. Meanwhile, the UL F-grade insulation system and 1000VAC dielectric strength form a solid safety barrier. The dual protection options of sealed and flux-resistant types can resist moisture and dust as well as flux corrosion during the soldering process. In addition, the three contact configurations of A/B/C, 3-24VDC wide voltage compatibility, 3.8g lightweight design and standard PCB mounting design allow the product to meet the small and medium power conduction needs of various scenarios such as small household appliances, small industrial control modules and precision electronic equipment without additional customization. With its unique advantages of "small and precise, accurate control and comprehensive protection", it has become a high-performance and cost-effective choice in the low-power relay market.
