Half-pitch Low-profile Stacking Connectors
XH4A
An Integrated Male/ Female Half-pitch
Stacking Connector with Board Space
Adjustable from 5 to 11 mm.
■ Board space can be adjusted from 5 to 11 mm in
1-mm increments. (Surface-mounted Connectors
can be adjusted from 5 to 9 mm in 1-mm increments.)
■ The product line includes DIP and Surface-
mounted Terminals (SMT) Connectors.
■ Integrated male/female Connectors.
■ All models incorporate fastening pins to secure
the terminals, thus preventing floating or falling
over during soldering.
■ The leaf contact construction resists bending.
■ The XH4A conforms to UL standards (file no.
E103202). (SMT Connectors not included)
■ Not mated with XH2 and XH3 Half-pitch Connec-
tors.
RoHS Compliant
■ Terminology
• SMT
The abbreviation of Surface Mount Technology.
• Integrated male/female Connectors
The male (plug) and female (socket) have the same
shape.
