Scanning Principle

The model MS 30 incremental linear encoder works with the imaging, photoelectric measuring principle and a single-field reflective scanning mothod. A 20-Um gold grating graduation is printed on a steel tape scale.

The light from an infrared LED with a small light emitting surface is columnated parallel by a condenser lens and directed through the scanning reticle to the scale.

When the scale is moved, relative to the encoder head, the light is modulated by the scale gratings and produces a periodic intensity signal that is converted into electrical signals by photo elements back in the encoder head.

Clean steel tape scale-optimal	Contaminated steel tape scale-unfavorable condition
