What this 16-position right-angle header does in a harness
The 4-794677-6: This is a 16-circuit, dual-row header from TE's Micro MATE-N-LOK series, on 3.00 mm pitch — the same pitch as the receptacle, so the board footprint and the mating half share the same grid.
Current rating and contact plating — what drives the limit
The current rating is listed as varying by wire gauge — in the Micro MATE-N-LOK system, the terminal and wire size set the ampacity, not the header alone. Tin is cost-effective for moderate mating cycles — expect 30–50 cycles before the contact resistance starts to drift.
Mating half and termination details
This header mates with Micro MATE-N-LOK receptacle housings that accept crimp terminals — the receptacle part numbers are in the 794617 series for the housing and 794606 for the pin terminal. The board lock adds mechanical retention during the soldering process and resists shear forces from the cable after assembly.
