Basic Knowledge of Photoelectric Sensors

What Is a Photoelectric Sensor

Photoelectric sensors detect presence of an object without contact, using light reflection.
They make an output signal according to an amount of received light that is reflected from a detection target.
They are mainly used to contribute to automation and labor-saving at manufacturing factories.
