Harwin M20-1060300 3-position cable housing

Off-board cable component with clearly labeled nominal geometry and harness documentation assets. Not a PCB solder footprint or qualified mating model.

Assets and use

The harness symbol is off-board (on_board=no). The mechanical envelope has zero copper pads and is excluded from PCB placement/BOM; it is not a solder footprint. The separately named mating PCB footprint is for Harwin M20-9990346, not this housing. STEP and GLB show original simplified geometry; inspect review/model-review.json for dimensions and omissions.

The 3-position empty housing uses 3 separately purchased M20-1180046 contacts. Nominal exterior is 7.82 × 2.50 × 14.00 mm; pitch 2.54 mm. It mates to 0.64 mm square pins with a specified 5.50–6.30 mm mating length. It is unpolarized. Use the drawn contact-one convention and verify orientation/continuity. Product temperature range is −25 to +85 °C. Electrical ratings apply only when assembled with specified contacts.

Internal passages are illustrative, not a dimensional tolerance model. Latches, cavity steps, chamfers and molded pin-one indication are not reproduced. Do not use this CAD to qualify mating fit.

Verification boundary

Native import, visual checks and physical harness qualification are tracked separately. Live wiki visual review remains pending because the task browser was closed. No factory connector is implied for the Sunon fan. No hardware, crimp or manufacturing release is claimed.

The copper-overlay hero generator rejects this legitimate zero-pad mechanical asset. The clean authored GLB is retained; no copper alignment pass is claimed. Tracked at component-hero issue1. An EDA device mapping from harness pins to nonexistent solder pads is deliberately not provided.
