Connectors of this type have contacts arranged in linear rows and an outline which is generally rectangular, rather than circular. They are used for creating pluggable connections directly between printed circuit boards without use of wire or cable, and can provide a large number of electrical connections in a relatively small space. For this reason they are commonly used to connect components of space-constrained systems.
