Harwin M20-7880546
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 has a box section design with a latch for secure positioning 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 a moulding and is available for horizontal or vertical mounting, with surface mount or through-board solder options. Plug mouldings come 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.
