Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If photoconductive cell rather than transistor
Light-dependent resistors (LDRs) without transistor amplification use different semiconductor structure.
If keyboard position sensor
Phototransistors designed for automatic data processing input devices classify accordingly.
If for drafting machine encoders
Position-sensing phototransistors for plotters/drafting machines fall under drawing instruments.
