The 3-292207-9 is a 19-position, single-row header from TE's Mini CT series, pitched at 0.059" (1.50 mm) — a tight enough spacing to save board real estate while keeping routing manageable for a 19-circuit wire-to-board interface. Rated for 50 VAC and a current that varies by wire gauge; the tin-plated contacts (39.4 µin on the mating surface) handle moderate mating cycles in a general-purpose environment.
Through-hole mounting with kinked solder tails
The contact length on the post side is 0.118" (3.00 mm), which gives enough standoff for the solder fillet to form properly. Compared to the 1-292164-1 from the CT series (2.00 mm pitch, right-angle, 11 positions), this Mini CT part is a finer-pitch, vertical-mount, higher-position-count option for denser layouts.
RoHS3 compliant (per TE's declaration) and housed in a UL94 V-0 rated glass-filled nylon, so it meets the flammability requirements for equipment inside an enclosure.
