A common BOM error is to order this housing and expect the contacts to arrive with it. The mating terminal is the TE Mini CT female socket crimp contact (typically 0.50mm to 1.00mm wire range, depending on the specific contact part number).
Position Count vs. the 1379217-6 Sibling
The closest same-series peer is the 1379217-6, which is also a Mini CT receptacle housing with a locking ramp, free-hanging mount, and female socket contacts. The key difference is position count: the 1-353908-1 carries 11 standard signal positions, while the 1379217-6 carries 5 signal plus 2 power positions (7 total). Both use the same 1.50mm pitch and crimp terminal family, so the wire-side tooling is shared.
