Two-position header for board-to-cable power or signal jumpers
This header accepts Universal MATE-N-LOK female socket contacts (sold separately) crimped to 20-18 AWG wire. The through-hole solder termination anchors the header to the PCB with 0.155" (3.94mm) post length — enough for standard 1.6mm boards with some clearance. The circular contact shape matches the standard Universal MATE-N-LOK pin geometry.
RoHS compliant per TE's standard material declaration. The tin-plated contacts and nylon housing are within current regulatory limits.
How the 2-position compares to higher-count siblings
The 643411-1 is the minimum-position variant in the Universal MATE-N-LOK header family. The 2-position here is the simplest choice for a single power or signal jumper where board space is not the constraint.
