MicroSpeed & MicroSpeed Power Connectors

TE Connectivity's ERNI MicroSpeed and MicroSpeed Power Connectors enable data transmission up to 25Gb/s with high signal quality and reliability. These connectors provide a versatile interconnect solution by providing 2-row, 3-row, and 7-row connector versions and 5mm to 20mm board-to-board spacing using different heights. The MicroSpeed Connectors feature low electromagnetic radiation and high immunity to interference. The connectors have a pitch of 1mm and are available in SMT (single contact) or THR (shield contacts) terminations. These connectors are ideal for next-generation communication standards like Ethernet 100Gbps, Optical Internetworking Forum (OIF), and USB 3.1.
