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. 2. MARKING OF THE CONNECTOR AND/OR PACKAGE (ORDER CODE). The marking (order code) shall appear on the package and shall be of the following style: M20 XXX XX XX Product Group Connector Style No. of Contacts per row Contact Finish The marking (order code) for a pin header variant shall appear on the package and shall be of the following style: M20 - XXX XXX X XX XX Product Group Dimension A Dimension B Connector Style No. of Contacts per row Contact Finish For details of Connector Style, Finish and No. Of Contacts per row, see individual drawings or Harwin catalogue. -2C00115 Date: 11-12-2012 C/Note: 11735 C00115 COMPONENT SPECIFICATION M20 SERIES CONNECTORS 3.
