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 (1.27
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.
■ The XH2 conforms to UL standards (file no.
E103202).
■ Not mated with XH3 and XH4 Half-pitch Connec-
tors.
RoHS Compliant

• Contact numbers are not printed on the
connectors. Use the triangular mark (▼)
as a guide when designing and mounting
to boards.
• On the mating side, the row of terminals
on the triangular mark side are called row
a, and the row on the other side is called
row b. The numbers are in the order
shown.
■ Precautions
Soldering
• The triangular marks on the plug and
socket must be aligned when mated. The
contact numbers on both sides must
match.
Automated soldering
Correct Use
Use tape to mask the Right-angle Terminal
Connector prior to automated soldering.
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.)
Masking tape
Automated Soldering
Conditions (Jet Flow)
1. Soldering temperature: 250±5°C
2. Continuous soldering time: Within 5±1 s
