High Speed Contacts

Amphenol Pcd High Speed Contacts include Quadrax, Twinax, and 75Ω contacts. Amphenol 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, low power consumption, and excellent EMI (electromagnetic interference) compatibility. Quadrax contacts meet EN3155 or ABS0973/0974 (ARINC600) standards. Amphenol 75Ω contacts feature 75Ω impedance, 0-3GHz frequency range, and meet EN3645 standards.
