XH2 Half-pitch Board-to-Board Connectors

Half-Pitch SMT Connectors: XH2

Allows High-density Mounting for
Electronic Devices. A Half-Pitch
Connector with a 1.27-mm Pitch for

  • A pitch of 1.27 mm for high-density mounting of double-row arrangements.
  • A quadruple-row staggered arrangement (1.27 mm x 1.905 mm) for board connection.
  • Leaf contact construction enables smooth mating and resistance to bending.
  • Space saving mating length of 3.1 mm.
  • Press fitting assures long-term contact quality. The gold/palladium plating has been improved for better contact reliability.
  • A special finish improves flux resistance (Straight Terminals only). Also it has fastening pins to standardize all the contacts.
  • Can be mounted to boards with screws.
  • Not mated with XH3 and XH4 Half-pitch Connectors.
  • See the "Standards certification / conformity list" for information on conformity to certification standards.
