• 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.
• The triangular marks on the plug and
socket must be aligned when mated. The
contact numbers on both sides must
match.
■ Precautions
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 auto-
mated 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±1 s
