Dimension Drawing
Mechanical Dimensions
| Dimension Parameter | Value (mm) |
|---|---|
| Protection Height | 360 |
| Total Height | 448 |
| Cross Section | 29 × 30 |
| Optical Axis Quantity | 10 |
| Optical Axis Pitch | 40 |
Protection Height Calculation
Protection Height = (Optical Axis Quantity – 1) × Optical Axis Pitch
For DPR-1040-NPN-NC:
(10 – 1) × 40mm = 360mm
NOTE: Protection height is defined as the distance from the center of the first beam to the center of the last beam.
