SOURIAU - SUNBANK Connection Technologies provides a large portfolio of circular connectors to answer the most stringent requirements in harsh environments. With metal, plastic or composite shells, contact layouts available in quadrax, twinax, coax or ELIO®, different locking mechanism such as threaded coupling, bayonet coupling or push-pull coupling and qualification to international standards that include MIL-DTL (QPL), EN, and many others, our circular connectors offer multiple product configurations designed for complex interconnect systems.
Circular connectors have been the standard for many years in harsh applications including aviation, transportation and energy. The integrated locking mechanism gives them an advantage over rectangular connectors which may need to be screwed into the panel, and they often provide a higher level of protection against water and dust ingress, especially when unmated.
