XH2 Half-pitch Board-to-Board Connectors

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

  • A pitch of 1.27 mm for high-density mounting of double-row arrangements.
  • A quadruple-row staggered arrangement (1.27mm 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.
  • The XH2 conforms to UL standards (file no.E103202).
  • Not mated with XH3 and XH4 Half-pitch Connectors.

Correct Use

Mating Compatibility

XH2 Half-pitch Connectors do not mate with XH3 or XH4 Half-pitch Connectors.

Special Finish for Preventing Flux Rise

XH2 Connectors (i.e., Straight Terminals) have a special finish that prevents flux rise. (The Connectors are designed for automated soldering. Brush coating flux from the back of the board applies too much flux and may nullify the special finish. Never use this method to apply flux.)

Soldering

Automated soldering
Use tape to mask the Right-angle Terminal Connector prior to automated soldering.


Automated Soldering Conditions (Jet Flow)

1. Soldering temperature: 250±5°C
2. Continuous soldering time: Within 5 s
