  9. Photoelectric sensor - Wikipedia

    en.wikipedia.org/wiki/Photoelectric_sensor

    Remote photoelectric sensors used for remote sensing contain only the optical components of a sensor. The circuitry for power input, amplification, and output switching is located elsewhere, typically in a control panel. This allows the sensor, itself, to be very small. Also, the controls for the sensor are more accessible, since they may be ...
