## Overall (mm)

| length | width | height |
|---|---|---|
| 35.0 | 18.5 | 21.0 |

**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

- Housing 35.0 × 18.5 face, 21.0 deep along the optical axis; the four edges parallel to the optical axis are R2.
- Back (mounting) face at 0, lens face at 21.0; the cable exits one long side face.
- Two M2 threaded holes in the back face, 4.0 deep, diagonal pair 28.0 apart along the length and 11.5 apart across, centred on the face (shown at Ø1.6 tap-drill size).
- Not modelled: the step in front of the lens windows and the cable.
- All dimensions are exact nominal millimetres, true size, with no tolerance added.

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

| feature | exact | mates with | fit | files |
|---|---|---|---|---|
| Back-face holes | 2 × M2, 4.0 deep, 28.0 × 11.5 diagonal | bracket with M2 screws (max 4 mm thread engagement) | designed | all |
