Songle's SLE (4117) Relay breaks away from the limitations of conventional medium-power relays that only offer "single compatibility." With its core highlights of "full-scenario circuit compatibility + improved design efficiency," it has become the preferred choice for electronic engineers and equipment manufacturers. Its biggest breakthrough lies in its six contact configurations (A/B/C/U/V/W), covering single-channel and dual-channel load specifications (up to 20A switching capability). Whether it's single-channel control of small home appliances, dual-channel linkage of industrial control modules, or complex circuit layouts of mid-range power equipment, it can directly and accurately match without additional circuit modifications or customized accessories, completely solving the pain point of "design rework due to contact mismatch." Combined with a standard PCB layout and a compact 12g size, it can easily integrate into high-density circuit boards and adapt to mass automated production processes, significantly shortening product development and assembly cycles. Meanwhile, the product also features stable operation over a wide temperature range of -40℃ to +105℃, low voltage drop loss, and a mechanical life of tens of millions of cycles. In addition, the reasonable pricing and customized services provided by the manufacturer directly without intermediaries make the entire process from circuit design and selection, mass production and assembly to long-term stable operation efficient and worry-free, making it a "key adapter component" that improves the flexibility of circuit design and production efficiency.
