(2) Reflective, fiber and others

(Emitter and receiver are in the same case)

The amount of light received or the amount of light emitted are adjusted, and the sensing distance is set.

* About the auto tuning amplifier, emitter current and the amount of light received are adjusted depending on a setting distance, and is set to the highest sensitivity.
