This 1.25mm pitch dual-in-line, board-to-
board connector. Double-sided, high-
pressure contacts and a housing locking
feature provide reliable connections.
Feature –––––––––––––––––––––––––
• A compact design to meet today’s needs
This small connector has a 1.25mm pitch dual-in-line
construction at both the mating and printed circuit board sides.
It has a mounting height of only 7.0mm and a thickness of
4.6mm.
• Positive housing lock provides a highly
reliable connection
The high-pressure, double-sided, fork type contacts and a
housing lock feature ensure continuity even when the
connector is subjected to severe vibration or shock.
• Polarized shrouded header
The polarized shrouded header prevents misinsertion or
distortion of the receptacle housing during mating. The rigid
mating between the plug and receptacle guarantees high
reliability during vibration or shock.
