High-Speed Contacts

Amphenol Socapex High-Speed Contacts feature Quadrax, Twinax, and 75Ω contacts. Twinax contacts are designed for use with Twinax cable (shielded twisted pair) in data bus systems and meet EN3155 or ABS1600/1607 standards (ARINC600). Amphenol Quadrax contacts offer several advantages for high data transfer rates, including low power consumption and electromagnetic interference (EMI) compatibility. Quadrax contacts meet EN3155 or ABS0973/0974 (ARINC600) standards. Amphenol 75Ω contacts feature 75Ω impedance, 0GHz to 3GHz frequency range, and meet EN3645 standards.
