The Molex C-Grid® SL Series of crimp connector is a great way to create a solid connection in a small footprint while still using a removable connector. These square connectors are perfect for connecting to standard square female sockets such as those found on 2.54mm / 0.1” pitch female headers and even Arduino header pins.

This specific part is the square male connector, these are crimped onto a wire and then inserted into the header. This contact also has a locking tab which prevents the wire from being unintentionally pulled from the connector housing.
