The TE Connectivity 794191-1 is a 6-circuit receptacle housing from the Mini-Universal MATE-N-LOK II series, a free-hanging (in-line) design with a 0.163" (4.14 mm) pitch across two rows. This series is a workhorse for internal wire-to-wire and wire-to-panel interconnects in appliances, automotive cabin electronics, and industrial control cabinets where the 4.14 mm pitch balances contact density against wire routing ease.
Contacts Are Ordered Separately — Here Is What That Means
The listing note 'Contacts Not Included' is not a footnote — it is the single most important procurement detail on this page. The contact termination is crimp, which means the wire is terminated to the contact with a crimp tool and die set before the contact is inserted into the housing. For a clean harness build, pair this housing with the TE Mini-Universal MATE-N-LOK II crimp contacts in the wire gauge your application requires — typically 20-16 AWG for the standard power contact, but confirm the specific terminal part number against your wire size. Section a sample crimp and count the strands captured; the wrong die height will pull out under load.
Pitch and Row Spacing — Why the 0.163" Grid Matters
Both the pitch between adjacent positions in a row and the row spacing are 0.163" (4.14 mm). That square grid means the 6 positions in 2 rows occupy a compact footprint — the contact centres are equally spaced in both X and Y. For a harness builder, this uniform spacing simplifies gang-crimping and cavity layout in multi-circuit connectors. The 4.14 mm pitch is wide enough to handle moderate wire gauges without the insulation crowding adjacent cavities, yet tight enough to keep the connector body small for panel cutouts.
