M20 SERIES CONNECTORS
1. DESCRIPTION OF CONNECTOR AND INTENDED APPLICATION.
A range of 2.54mm (0.1”) pitch connectors, having 0.64mm (0.025”) square pins and sockets suitable for
interconnecting board to board and board to wire.
The socket is a box section design with a latch to locate and hold in an insulated housing. Terminations are
available for wire crimp, through board solder or surface mount in either horizontal or vertical mounting.
The plug pin is held in a moulding, and is available for either horizontal or vertical, surface mount or through
board solder mounting. Plug mouldings are available in unlatched or latched versions. Contacts may be
gold. Surface mountable pin headers are available in single and double row, vertical and horizontal
variations.
