XH2 Half-pitch Board-to-Board Connectors
1
Allows High-density Mounting for
Electronic Devices. A Half-Pitch
Connector with a 1.27-mm Pitch for
Compactness.
■ A pitch of 1.27 mm for high-density mounting of
double-row arrangements.
■ A quadruple-row staggered arrangement (1.27
mm x 1.905 mm) for board connection.
■ Leaf contact construction enables smooth mating
and resistance to bending.
■ Space saving mating length of 3.1 mm.
■ Press fitting assures long-term contact quality.
The gold/palladium plating has been improved for
better contact reliability.
■ A special finish improves flux resistance (Straight
Terminals only). Also it has fastening pins to stan-
dardize all the contacts.
■ Can be mounted to boards with screws.
■ The XH2 conforms to UL standards (file no.
E103202).
■ Not mated with XH3 and XH4 Half-pitch Connec-
tors.
