Board-In Connectors

Molex's board-in connectors are available in a variety of pitches, configurations, and circuit sizes

Image of Molex's Board-in Connectors Ideal for simple and permanent connections, Molex's board-in connectors provide a wide range of pitch options, mating configurations, and circuit sizes that offer reliability versus hand-soldering.

When choosing a connection type, designers often need to consider trade-offs such as cost, assembly needs, and whether the connection needs to be unmated. In cases where a simple connection will suffice, questions of reliability need to be addressed when comparing hand-soldering to other soldering methods.

Molex's board-in connectors meet the requirements of a cost-effective easy-to-assemble connection that does not need to be unmated on at least one end. Compared to competitive board-in types, Molex offers the widest range of pitch options, mating configurations, and circuit sizes.
