• 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
XH3 Half-pitch Connectors do not mate
with XH2 or XH4 Half-pitch Connectors.
Flux Rise
These Connectors were designed for auto-
matic soldering. If you use a foaming
device or brush on flux from the front side,
the amount of applied flux will increase and
may cause flux rise. Do not use these
methods 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
(Be sure to wash the board after contin-
uous soldering is completed.)
