CONNECTOR
2.5mm pitch/Board-to-board connectors
This 2.5mm pitch connector is used
to interconnect printed circuit boards.
It easily resists distortion during mating,
thus ensuring reliable contact, even under
adverse conditions.
• High contact pressure
• Box-shaped shroud
• Secure locking on printed circuit boards
• Vertical, horizontal and parallel mounting
• Interchangeability
