Having been deeply engaged in relay manufacturing for nearly three decades, Chengyuan Chuangke has expanded its product range.
Recently, Ningbo Chengyuan Chuangke Electronics Co., Ltd. announced the official launch of a new series of reed relays, further enriching the company's product line. As a professional manufacturer specializing in relays for nearly three decades, Chengyuan Chuangke's newly launched reed relays draw on the company's expertise in designing precision electromagnetic components, sealing packaging processes, and contact material research. They aim to provide reliable signal switching solutions for high-end applications such as automated testing equipment, medical electronics, instruments and meters, and new energy.
The bimetallic relay, with its unique structural design - sealing the gap spring inside a glass tube and achieving instantaneous contact closure or release through the magnetic field generated by the coil - has outstanding advantages such as fast operation speed, sealed contact isolation, long lifespan, and small size. It is particularly suitable for precise switching scenarios that require high reliability and long service life. The Chengyuan Chuangke R&D team, based on the application requirements of instruments and meters, has comprehensively optimized the product to ensure its stable and reliable performance in micro-signal switching and high-frequency operations.
Strictly control the entire process quality to ensure stability and reliability.
The core of the reed relay lies in the sealing performance of the reed switch and the reliability of the contacts. Chengyuan Chuangke, relying on nearly three decades of manufacturing experience, strictly controls the quality from the very beginning by selecting instrumentation-grade reed switches. This ensures that the products have high insulation resistance (>10¹¹Ω) and stable low contact resistance. During the production process, the company strictly adheres to the quality policy of "honesty as the foundation and quality as the soul", using automated winding and packaging equipment. Each relay is subjected to rigorous dynamic contact resistance tests, withstand voltage tests, and life verification to ensure that the factory products can meet the long-life requirements of hundreds of millions or even billions of operations.
To meet the requirements of high-density PCB layout, Chengyuan Chuangke's new bimetal relay adopts a compact SIL or DIP packaging design. Some models support surface mounting, which can effectively save circuit board space. At the same time, the company can also choose to equip an internal magnetic shielding structure, significantly reducing magnetic interference and enabling stable parallel operation in high-density matrix and multi-channel multiplexing applications.
Tailor services flexibly based on customer needs
Thyristor relays are widely used in semiconductor testing equipment, battery management systems, solar inverters, medical analysis instruments, and safety control circuits, among other fields. Different applications have different requirements for the switching voltage, current-carrying capacity, creepage distance, and packaging form of the relays. The Chengyuan Chuangke R&D team can quickly respond to customer needs and provide customized solutions for coil voltage, contact form, pin layout, and even internal shielding, helping customers achieve the best balance between performance and reliability in demanding application scenarios.
The company's executive stated: "The bimetal relay is an important step for Chengyuan Chuangke in completing its product portfolio and moving towards the high-end testing and measurement field. We will continue to be driven by technological innovation and, based on our 30-year manufacturing experience, dedicated to providing more reliable and precise relay solutions for global customers, and becoming a trustworthy partner."
