DESCRIPTION OF CONNECTOR AND INTENDED APPLICATION A range of 1.27mm pitch connectors, jumper sockets and IDC cable connectors, comprising vertical surface mount, vertical and horizontal throughboard, plugs and sockets of varying heights. Board-to-board spacing and configuration is obtained by the selection of an appropriate height plug and socket.   2. M50 connectors are spaced 1.27mm between rows and based on 0.40mm square/round pins. M52 connectors are spaced 2.54mm between rows and based on 0.46mm square pins. RATINGS Note:  Individual components may exceed below ratings – check individual customer information sheets.  For M50 Pin Header variants, use the relevant specifications for M50-350, 360 and 390. For M52 Pin Header variants, these are specified as “M52-PH”. 2.1. Material & Finish All materials are listed on individual drawings.
