This EMI shielded circular connector is designed to protect signal integrity in complex electronic environments. Its metal shell structure, shielded contact compatibility, and reliable coupling mechanism help reduce electromagnetic interference while maintaining stable electrical connection. The connector supports coaxial and shielded contacts in 12#, 10#, and 8# cavity positions, making it suitable for high-reliability signal, shielded transmission, and mixed-contact applications.
