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 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.
* Excluding SMT connectors
■ 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.

• The triangular mark (▼) and contact num-
• On the mating side, the row of terminals on the
raised reference point side are called row a, and
the row on the other side is called row b. The
numbers are in the order shown.
• XH4A Half-pitch Connectors are integrated
male/female connectors. The contact numbers
on row a correspond to the contact numbers on
row b. Be careful when using these connectors
because they function slightly differently from
separate male and female connectors (i.e.,
Plugs and Sockets).
■ Precautions
Mating Compatibility
Be sure to wash the board after automated
soldering is completed.
Correct Use
XH4 Half-pitch Connectors do not mate
with XH2 or XH3 Half-pitch Connectors.

Soldering Conditions
XH4A Half-pitch Connectors are male/
female connectors with integrated plugs
and sockets.
Straight DIP Terminals (Automated Soldering)
Refer to Contact Numbers above when
designing boards.
(2) Continuous soldering time: Within 5±1 s
bers are not printed on the connectors.
Use the raised reference point used to
prevent reverse insertion as a guide when
designing boards.
(1) Soldering temperature: 250±5°C
Recommended reflow conditions
Pre-heat temperature: 150±10°C
Pre-heat time: 60 to 120 s
Soldering temperature: 200 to 240°C
Soldering time: Within 30 s
