The TE Connectivity 292182-8 is a Mini-Drawer plug with 12 positions arranged in 2 rows. It carries a mixed contact layout of 8 signal and 4 power circuits, with only 8 positions loaded from the factory.
In a Mini-Drawer used inside an enclosure, the gold layer handles the signal-level currents without fretting, while the 4 power contacts carry the higher-current rails. The 8 unloaded cavities let you populate only the circuits your BOM needs — the housing itself is a 12-position shell, but you get an 8-position connector out of the box.
