Amphenol CIT’s Card Edge Connectors Contact System is designed for high-speed, high-density applications. Card Edge Connectors have a smooth mating surface area, which reduces the wear and tear of contacts and increases the durability and life-span of the contact system. They also lower insertion and withdrawal forces while supporting data rates up to 32 Gbps with excellent signal integrity. These connectors are suitable for multiple applications (like cable-to-board and board-to-board) with various PCB thickness profiles. In addition to increased durability and extended lifecycle, Card Edge Connectors Contact Systems offer superior electrical performance (e.g., lower insertion loss, low return loss, and perfect impedance matching), compared to similar contact systems. The contact pins parallel each other and, when housed in the plastic insulator, offer low crosstalk and coupling, improving the overall interconnect performance. The contact pin design and grounding are optimized for 100-ohm signaling systems.
