The 3M 3000 series connector header, part number 3431-1202, is a right-angle, through-hole component featuring 34 positions with a fine pitch of 0.100" (2.54mm). This shrouded header utilizes male pin contacts made from copper alloy with gold plating (30.0µin) on the mating surfaces for low contact resistance, and tin-lead plating on the posts for reliable solder termination. The insulation material is a glass-filled PCT and polyester blend, rated UL94 V-0 for flammability. Designed for board-to-board or cable applications, it supports a current rating of 1.75A and operates within a temperature range of -55°C to 105°C. Keying slots and mounting flanges facilitate secure assembly. This component is commonly found in industrial automation, telecommunications, and consumer electronics sectors.
