429-41-240-41-540000

Headers, Receptacles, Female Sockets Overview

The Mill-Max 429-41-240-41-540000 is a standard socket header connector designed for board-to-board stacking applications. It features a dual-row configuration with 40 positions and a 0.100-inch (2.54mm) centerline spacing. The unit utilizes through-hole solder cup termination for secure PCB mounting. Contacts are constructed from copper alloy with gold plating to ensure reliable signal transmission. The insulator is made of black PCT material, rated UL94 V-0 for flame resistance.
