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.
