Component Specification C00120 M20 Series Connectors November 2022 SECTION TITLE PAGE 1 Description of Connector and Intended Application 2 2 Ratings 2 Appendix 1 Gauges 4 // HARWIN.COM C00120 Component Specification – 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. 2. RATINGS Note:  Individual components may exceed below ratings – check individual customer information sheets.  Ratings for all M20 Throughboard Pin Headers, including Pin header variants, are detailed below as “M20-PH”. 2.1.
