The N3428-6202RB is a 20-pin, 3000 series four-wall header designed for reliable board-to-board connections. It features a high-temperature black PCT insulator suitable for no-lead soldering processes and straight solder tails for mounting on 0.062" thick PCBs. The copper alloy contacts are plated with 30 µ" of gold in the wiping area and matte tin on the tails, ensuring excellent conductivity and solderability. Equipped with short roll pin latch/ejectors for secure mating, this header is ideal for applications requiring robust interconnects with polarization features.
