J599-26WB35SN MIL-DTL-38999 Circular Electrical Connector with Socket Contacts
EMI Shielded Series III Circular Connector
The EMI Shielded Series III Circular Connector is a high-performance interconnect solution developed for complex electronic systems that require stable signal integrity and reliable electromagnetic interference protection. Constructed with a precision metal shell and designed to accommodate shielded and coaxial contact options, this connector helps protect internal circuits from external electromagnetic disturbance while supporting stable and efficient electrical transmission. Its dependable coupling mechanism ensures firm mating, excellent mechanical retention, and consistent performance in demanding working environments. With support for shielded contacts in 12#, 10#, and 8# cavity positions, the connector offers flexibility for mixed-contact layouts and customized signal configurations. It is well suited for high-reliability applications such as industrial equipment, communication systems, control systems, test instruments, automation platforms, and shielded transmission assemblies requiring durability, EMI protection, and long-term operational stability.
