## Overall (mm)

| length | width | height |
|---|---|---|
| 50.0 | 38.0 | 20.9 |

**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: body centre; bottom (screw-hole face) at 0, label face at 20.9 (nominal 21). x is measured from the −x end as on the drawing.
- Body 50.0 × 38.0 × 20.9. Four M2 self-tapping screw holes in the bottom on a 45.0 × 33.0 pattern, modelled Ø2.0 × 4.0 deep (depth not given).
- Air face (one long side): a row of four Ø2.5 inlet openings 2.45 below the top, the first 6.0 from the −x end, 4.0 apart; fan outlet grille R6 to R9 centred 35.8 from the −x end at mid-height.
- Connector face (the other long side): opening 17.0 wide × 4.9 tall, its right end 5.5 from the +x end, at mid-height.
- Not modelled: the shell corner radii, the ribs of the fan grille and the interior.
- 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)

| feature | exact | mates with | fit | files |
|---|---|---|---|---|
| bottom screw holes | 4 × Ø2.0 on 45.0 × 33.0 | M2 self-tapping screws through the enclosure floor | designed | all |
| air inlet and fan outlet | 4 × Ø2.5 inlets; outlet R6–R9 at 35.8 from −x | matching ports in the enclosure wall | designed | all |
| connector opening | 17.0 × 4.9 | sensor cable plug | designed | all |

## Sizes

| hole | x (mm) | y (mm) | Ø × depth (mm) |

## Questions

**How big is the PMS5003?**

50.0 × 38.0 × 21 mm (20.9 mm as drawn).

**What screw pattern does the PMS5003 use?**

Four M2 self-tapping screw holes in the bottom on a 45 × 33 mm pattern.

**Where are the air inlet and outlet?**

Both on one long face: four inlet holes 2.45 mm below the top starting 6 mm from one end, and the fan outlet (R6–R9) centred 35.8 mm from that end at mid-height.
