Harwin M20-9990945
M20 Series Connectors
A range of 2.54mm (0.1") pitch connectors featuring 0.64mm (0.025") square pins and sockets. Designed for interconnecting board-to-board and board-to-wire applications. The socket features a box section design with a latch for secure location within an insulated housing. Terminations are available for wire crimp, through-board solder, or surface mount in horizontal or vertical orientations. The plug pin is held in an 8-moulding and is available for horizontal or vertical, surface mount, or through-board solder mounting. Plug mouldings are offered in unlatched or latched versions. Contacts may be gold plated. Surface-mountable pin headers are available in single and double row, vertical and horizontal variations.
