The sensor that MOST-Likely uses a beam of light to control the primary circuit is the:
A)Hall-effect sensor
B)MR sensor
C)photoelectric sensor
D)crank angle sensor

Question

Quizplus · Accepted Answer

A photoelectric sensor uses a beam of light to detect the presence or absence of an object and can be used to control a primary circuit such as a lighting system. Hall-effect and MR sensors measure magnetic fields, and a crank angle sensor measures the position and rotation speed of a crankshaft in an engine.
