ΦCA ΦGS02 ΦHTMA series circular electrical connectors

ΦCA, ΦGS02, ΦHTMA series circular electrical connectors

       ΦCA, ΦGS02, and ΦHTMA Series Circular Electrical Connectors are all high-reliability circular connectors primarily used in military, aerospace, and specialized industrial fields. The ΦCA Series features a bayonet quick-coupling mechanism, offering strong versatility and a wide range of specifications, making it suitable for ground equipment and instrumentation. The ΦGS02 Series typically adopts a push-pull structure, with some models incorporating filtering functions, making it ideal for electronic systems with high electromagnetic interference resistance requirements. The ΦHTMA Series utilizes glass sealing technology, providing high-temperature resistance and strong hermeticity, specifically designed for extreme environments such as aircraft engines and downhole exploration. Each series has its unique characteristics, collectively forming a comprehensive circular connector system covering general connection, signal filtering, and high-temperature hermetic sealing for all scenarios.
