Photoelectric rotation detector
LG-930
The LG-930 is a non-contact rotation detector that uses red visible light as a light source and detects reflected light. It is typically used with a reflective mark (sold separately) attached to the rotation axis. It is compact, measuring 76.5 mm in length, and can detect objects from a maximum distance of 200 mm.
