Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If paired with opposing IR emitter
Phototransistor with integrated emitter becomes optoelectronic coupler, different tariff treatment.
If for industrial process control use
UV sensors designed for monitoring industrial processes may classify as level/pressure instruments.
If component of HVAC UV sterilization system
UV sensors integral to complete refrigeration/sterilization equipment classify with machinery.
