XH3/XH4/XH2
Half-pitch Connectors Series
1.27-mm Contact Pitch
Greatly Contributing to High-density Mounting of Electronic
Components and Miniaturization of Electronic Devices
Stacking heights supported in the range 5 to 20 mm at 1-mm increments.
Leaf contact structure ensures high resistance to twisting force and
smooth connection and disconnection.
XH2/XH3: Au/Pd-plated contacts with an engagement length of 3.1 mm
ensure high contact reliability.
Snap-on terminal for easy connection to the PCB.
Housing with standoff construction for improved soldering quality and
easier cleaning (except 1 and 2-mm increment models).
XH2/XH3/XH4 DIP model: Approved by EN, IEC, UL, and CSA standards.
Product lineup includes fine-fit models that are mounted to PCBs
with ease with no soldering.

Fine Fit
The term " fine fit " (generally known as " press fit " ) refers to the
technique where the connector terminal are pressed into the
through holes of the PCB to connect the PCB and connector
electrically and mechanically with the spring pressure of the
terminal.
The connector is connected with no solder, eliminating the
soldering stage usually required with connectors. Furthermore
the PCB is free of thermal load or flux, thus contributing to cost
reductions and improvements in contact reliability.
