M50 AND M52 SERIES CONNECTORS
1. DESCRIPTION OF CONNECTOR AND INTENDED APPLICATION.
A range of 1.27mm pitch connectors, jumper sockets and IDC cable connectors, comprising vertical surface
mount, vertical pc tail, horizontal pc tail, plugs and sockets of varying heights. Board-to-board spacing and
configuration is obtained by the selection of an appropriate height plug and socket. M50 connectors are
spaced 1.27mm between the rows, and are based on 0.40mm square or round pins. M52 connectors are
spaced 2.54mm between the rows, and are based on 0.46mm square pins.
