The N3429-6202RB is a 3M Four-Wall Header connector from the 3000 Series designed for high-density interconnect applications with 26 pins and .100" × .100" latch/ejector spacing. The header features a glass-filled polyester (PBT) insulator body in gray color with copper alloy contacts plated with 100 µ" nickel underplating and 30 µ" gold wiping area, meeting UL 94V-0 flammability standards. It supports military polarization with 3M's 3518 & N3518 polarizing keys and includes optional ejector latches, mounting holes for board securement, and polarizing posts. The connector is available in both straight and right-angle configurations with dimensions of 2.065" (52.45 mm) length, 1.905" (48.36 mm) width, and features ABC polarizing notches for secure mating. High-temperature insulator options (PCT) are available for lead-free and reflow soldering operations, making this header suitable for military applications, telecommunications, and industrial control systems requiring reliable, polarized connections.
