• 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
