XJ8/XG8S/XG8T
Low-profile Circuit Jumper Connectors
• Low profiles of 5.8 mm (XJ8) and 6.8 mm (XG8S/T).
• 2.54-mm grid can be mounted horizontally or vertically.
• Chose from Single-row, Double-row or Triple-row Connectors.
• Designed for easy insertion and protection against
accidental removal.
• Highly-reliable Jumper with 2-point contacts (XJ8A).
• All versions employ flame-resistant materials for base and
housing.
• XJ8 Connectors conform to UL standards (file no. E103202)
and CSA standards (file no. LR 62678).

Precautions

Correct Use
Dividing the XJ8 / XG8S / XG8T
The above mentioned models may have the number of terminals and
rows reduced prior to pcb assembly, using the following method:
•
Plugs can be easily cut along the V-groove. Using a Cutter, make a
cut on the slot as indicated by the dotted line in the diagram. Then
fold the Plug manually in the direction of the arrows.
Automated Soldering Conditions (Jet Flow)
1.
Soldering temperature: 250 ±5°C
2.
Continuous soldering time: Within 5 s
(1) Using a cutter,
make a cut along
the dotted line.
(2) Manually fold in
the direction of the
arrows.
Mounting Example
•
Jumper Socket should be inserted so that the arrow points down.
