The N3432-6302RB is a 3M Four-Wall Header connector from the 3000 Series designed for high-density interconnect applications with 40 pins arranged in a 0.100" × 0.100" grid pattern. The header features optional latch/ejector mechanisms, polarizing notches (ABC configuration), and is available in both straight and right-angle mounting orientations. The insulator is constructed from glass-filled polyester (PBT in gray or PCT high-temperature option in black), with copper alloy contacts plated with 100 µ" nickel underplating and 30 µ" gold wiping area. The connector supports multiple contact tail options including solder tails for 0.062" thick PC boards (Dim E: 0.112" ± 0.010") and thicker boards up to 0.125" (Dim E: 0.155" ± 0.010"), with pin cross-section of 0.0245" ± 0.0005". This header is suitable for military applications with 3M's 3518 & N3518 polarizing keys, supports high-temperature reflow soldering operations, and includes optional mounting hardware (stainless steel screws and bolts) for secure board attachment.
