Product Details
Hirose DH Series Shielded High Speed Interface
DH Series is an impedance controlled interface connector for high speed transmission. It has a 1mm contact mating pitch. This, coupled with a 0.5mm mounting pitch, makes for a more compact, lower-profile, higher-density alternative to conventional half-pitch interface connectors. Depending on the cable, the DH Series caters for speeds up to 2.5Gb/s. Applications include enterprise networking, industrial, telecom and datacom.
