All models of the S-series push-pull self-locking connectors are waterproof when mated and achieve an IP68 (or at least IP66) protection rating when correctly assembled with compatible cables. They share the same insulator as the B-series and feature: a fast push-pull self-locking system; a robust housing design suitable for extremely harsh environments; a positioning pin system ( for standard positioning pins) for connector alignment; multi-core options from 2 to 40 pins; and waterproof connections (IP66/IP68). This series is widely used in precision electronic instruments, portable medical devices, photographic and video equipment, smart homes, communication digital products, and laboratory testing equipment. It is particularly suitable for applications such as internal wiring in slim devices, cable connection in portable mobile devices, installation in confined spaces, and high-frequency, rapid mating. It is a commonly used high-quality connector in the high-end precision electronics industry.
