Optical Structure Reference

Protection Height: 380 mm — (Beam Quantity − 1) × Optical Axis Pitch = (20 − 1) × 20 mm
Total Height: 459 mm — Protection Height + End Cap Dimensions
Beam Count: 20 optical beams
Optical Axis Pitch: 20 mm
Resolution: 10 mm
Detection Distance: 0.1–3 m

Beam Spacing Example

The optical axis pitch of 20 mm represents the distance between the centers of adjacent infrared beams.

Beam Position	Distance from Top (mm)
Beam 1 (Top)	0
Beam 2	20
Beam 3	40
…	…
Beam 20 (Bottom)	380
