Board-to-board & wire-to-board connectors
Board-to-board and wire-to-board connectors are used to create reliable electrical connections between circuit boards, or between cable and circuit board, in electronic systems. They are a key component in everything from industrial automation and automotive engineering to medical technology and consumer electronics.

Differences and similarities
Card to card
Board-to-board connectors allow direct interconnection of two printed circuit boards and are often used in modular and compact designs where space, signal integrity and reliability are critical.
Card to cable
Wire-to-board connectors are used to connect cables to a printed circuit board and provide flexibility in design, installation and service.
Similarities of the contacts
Common to both contacts is the focus on:
- Safe and stable signal and power transmission
- Compact formats and different pitch distances
- High mechanical resistance and long service life
- Customisation for demanding environments and applications
