The TE Connectivity 1-292215-8 is an 18-position plug-to-plug adapter from the Mini CT series, designed to join two male plug connectors inline at a 0.059" (1.50mm) pitch. It serves as a panel-mount pass-through for wire harnesses where a break-before-make or bulkhead transition is needed. The snap-in mounting secures it into a panel cutout without additional hardware, making it a practical choice for harness routing in tight enclosures.
The 1.50mm pitch is the tightest fit constraint: it determines the board footprint if the adapter mounts to a PCB, and it sets the spacing for the mating plug housings. Confirm that your harness plugs and panel cutout align with this single-row layout before committing the BOM line.
Panel mount with snap-in retention means the adapter clips into a rectangular cutout and holds without screws or brackets. This is typical for bulkhead applications where the harness passes through a chassis wall. The single-row design keeps the insertion force manageable during mating, but the snap-in ears need the correct panel thickness to lock properly — verify the panel thickness against the product drawing.
