Hirose DH Series Interface Connectors NEW! Hirose has expanded its DH Series I/O connectors to include more contact sizes, lock types, and orientation styles (right angle and straight).Hirose introduced the DH Series as a line of shielded, impedance-controlled interface connectors for high-speed data transmission. Featuring small pitch sizes (0.5mm mounting pitch and 1mm contact mating pitch), the DH Series is a more compact, lower-profile, higher-density alternative to conventional half-pitch interface connectors. The Hirose DH Series 1mm Pitch Interface Connectors offer a D-shaped interface design to resist wrenching forces, through-hole style metal fittings to increase retention to the PCB, a unique contact arrangement for IDC termination, excellent shielding for EMI prevention, and transmission rates up to 2.5 Gb/s when coupled with a high speed cable. Available with four different locking styles. The Hirose DH Series 1mm Pitch Interface Connectors are ideal for enterprise networking, industrial, telecom, and datacom applications requiring higher data speeds.
