It uses a friction lock to hold the mate — a latch you can release with a pick on site if you need to break the connection for rework. The housing is natural PA66 nylon, rated for -40°C to 90°C operation, so it handles cabinet interiors and mild industrial environments without issue. Note the row count: 2 rows for only 2 positions, which means each row carries one cavity — a layout that simplifies wire routing but does mean the harness builder needs to keep track of which cavity is which.
This housing ships without contacts. If you are wiring a new harness, grab the terminals before the housing lands; if you are repairing an existing loom, check that the contacts already in the harness are the correct series. The 0.163" (4.14 mm) row spacing is tight enough that the wrong terminal may not seat fully.
The 794894-1 is listed as Active — no end-of-life or last-time-buy notice on record. It is RoHS compliant. No official second-source cross-reference exists in the evidence, so stick with the TE part number for BOM consistency.
