DH 1mm Pitch Interface Connectors



Hirose introduced the DH Series as a line of shielded, impedance-controlled interface connectors for high-speed data transmission. Featuring small pitch sizes (the 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 to meet various application requirements.


Features
  • Compact design yields approximately 50% reduction in mating face area over conventional, general purpose half pitch connectors
