Engineering High-Reliability Connectors & Harnesses Since March 2007
Guangzhou Hengyu Electronic Technology Co., Ltd. (Brand: Hengyu Electronic) is located in Guangzhou Science City ("China's Silicon Valley") within the Greater Bay Area, specializing in R&D and precision manufacturing of connectors, RF interfaces, and turnkey cable harnesses.
Guangzhou High-Tech Enterprise Driven by Continuous R&D Innovation
Founded in March 2007, Guangzhou Hengyu Electronic Technology Co., Ltd. (Brand: Hengyu Electronic / 恒钰电子) is located in Guangzhou Science City ("China's Silicon Valley") within the Guangdong-Hong Kong-Macao Greater Bay Area. Relying on regional electronic information industry clusters, Hengyu has spent nearly two decades deep-cultivating the interconnect technology field.
Adhering to technology innovation as our core driver, Hengyu invests over 10% of annual sales revenue into new product R&D every year. Backed by the National Science & Technology Innovation Fund and certified as a "Guangdong High-Tech Enterprise", our senior engineering team holds key national invention patents—including right-angle cable shielding overmolding, rectangular crown spring contacts, and circular environmental sealing structures.
Operating from a 20,000 m² smart manufacturing campus, our high-reliability connectors and custom cable assemblies are trusted by leading equipment OEMs across aerospace, aviation, telecommunications, LED displays, marine/shipbuilding, rail transit, power grid, and industrial automation.
