This 2.5mm (.098") pitch connector is
used to interconnect printed circuit
boards. It easily resists distortion during
mating, thus ensuring reliable contact,
even under adverse conditions.
Features –––––––––––––––––––––––
• High contact pressure
This vibration-resistant, double-beam contact provides high
contact pressure and thus eliminates contact bounce during
vibration or shock.
• Box-shaped shroud
The four-sided shrouded header prevents the socket housing
from being misinserted or distorted during mating. The slots in
the header's shroud fit snugly into the receptacle housing,
guaranteeing a vibration-proof coupling. And the serrated
square posts are pressure-fit to prevent flux from entering
during soldering.
• Secure locking on printed circuit boards
The solder tails of both the plug and receptacle have board
retention features. This ensures secure mounting and
accurate location during soldering.
• Vertical, horizontal and parallel mounting
Both top-entry and side-entry receptacles and shrouded
headers are available, thus allowing printed circuit boards to
be connected vertically, horizontally or parallel to the mother
board.
• Interchangeability
The shrouded header is interchangeable with the XH wire-to-
board crimp style connectors, the NR, NRD and BR wire-to-
board insulation displacement connectors.
