The 0.100" (2.54mm) pitch matches the standard MTA-100 header footprint, and the white housing carries a feed-through feature for daisy-chaining multiple connectors on the same cable run.
IDC Termination and Wire Handling
This works for 24 AWG solid or stranded wire, and the feed-through feature allows the cable to pass through the connector body, so you can terminate multiple receptacles along a single ribbon cable without cutting it. The right-angle cable exit keeps the wire bundle parallel to the board edge, which helps in tight enclosures where straight-out cable routing would hit the wall.

Tin is the right choice here because the target application is a low-cycle, permanent-install harness in a controlled environment.
