In a photoelectric sensor, which component detects the light signal after emission?

Explanation:
The detecting element in a photoelectric sensor is the receiver. After the emitter sends out the light beam, the receiver, which is a photodetector (like a photodiode or phototransistor), senses the light and converts it into an electrical signal that the system can process. The transmitter is the light source, the housing is just the outer shell, and the contacts are the electrical connections. So detecting the light signal after emission is the job of the receiver.
