Features ––––––––––––––––––––––––
• A compact high-density design to meet
today's needs
The mating part has a 1.25mm (.049") pitch, single row
construction. To meet the needs for high-density design, this
compact, low-profile connector is only 6.8mm (.268") high and
3.6mm (.142") wide when mounted on the printed circuit board
- roughly 40 percent smaller than our second smallest 2.0mm
(.079") pitch model.
• Secure locking and reliable connection
This connector features a high pressure, dual beam, fork
contact. The secure housing lock ensure a highly reliable
connection even under the severest environmental conditions.
• Box shaped housing
Box-shaped housing prevents misinsertion. The plug fits
securely into the mating receptacle for greater resistance to
The JE connector is a compact, high-
density, board-to-board connector only
6.8mm (.268") high and 3.6mm (.142") wide.
Its mating part has a 1.25mm (.049") pitch,
single row construction. High contact
pressure dual beam fork contacts are
combined with a housing lock mechanism
to ensure a reliable connection.
vibration.
• Easy mounting and no flux problems
The contact solder tails can be easily clinched. This allows
efficient, secure mounting onto printed circuit boards. The
bottom of the connector housing is designed to prevent flux
from adhering.
