42 Half-Pitch Connectors XH2

Half-Pitch Connectors

XH2

Allows high-density mounting for

electronic devices.

A half-pitch connector with a pitch of

1.27 mm (0.05 in.) for compactness.

• A pitch of 1.27 mm (0.05 in.) for high-density mounting of

double-row arrangements.

• A quadruple-row staggered arrangement (1.27 mm x

1.905 mm) (0.05 in. x 0.075 in.) for board connection.

• The bellows contact design, enables smooth mating and

resistance to bending.

• Space saving mating length of 3.1 mm (0.12 in.).

• Positive contact locking assures long-term contact quality.

The gold/palladium plating has been improved for better

contact reliability.

• A special finish prevents flux rise. Also, it has fastening pins

to standardize all the terminals.

General Information

■Contact Numbers

•Contact numbers are not printed on the connectors. Use the trian-

gular mark (indicates contact 1) as a guide when mounting to a

board.

•On the mating side, the row terminals on the triangular mark side

are called row a, and the other side is called row b. The numbers

are in the order shown.

•The triangular marks on the plug and the socket should be aligned

when mated. The contact numbers on both sides should match.

■Precautions

Automated Soldering

Use tape to mask the right-angle connectors before automated-sol-

dering.
