## Overall (mm)

| length | width | height |
|---|---|---|
| 35.0 | 21.25 | 13.5 |

**Exact dimensions.** Every file is drawn at true size with no tolerance added. The holes and pins that meet another part are listed below under Mating features, with the fit each joint needs; open those by your process's clearance before making the part.

## Notes

- Datum: housing centre; back face (ear plane) at 0, optical axis along +z, lens face up.
- Body 26.50 × 21.25 × 12.0; two ears 2.0 thick flush with the back face, ear tips 35.0 apart overall.
- Ear holes Ø2.2, 30.50 apart, 9.0 below the top face of the body (y +1.625 from the body centre).
- Two lens rings Ø10.50 × 1.5 on the front face, 10.50 apart, on the same line as the ear holes; total depth 13.5 (the datasheet text gives 12.5).
- Not modelled: the 6-pin connector recess in the top face and the body's corner rounding.
- Dimensions are exact nominal (true size), no tolerance added.

## Mating features (exact size; open press / slide / run / socket by your process clearance, leave designed and clamp as drawn)
