Answer: B
Share your understanding of this question with the correct explanation.
Explanation:
The statement is false. An inductive proximity sensor is actuated only by conductive materials and is not affected by nonconductive materials.
Inductive proximity sensors work based on electromagnetic principles. They generate an electromagnetic field around the sensing face, and when a conductive object comes into the sensing range, it disturbs the electromagnetic field, triggering the sensor’s output.
Nonconductive materials, such as plastics, wood, paper, and liquids, do not significantly affect the sensor’s electromagnetic field. Therefore, they do not actuate the sensor, and the sensor will not detect their presence.
Conductive materials, on the other hand, such as metals, have an effect on the sensor’s electromagnetic field, and when they come close to the sensor’s sensing face, they cause a change in the field, leading to the sensor’s activation or actuation.
In summary, an inductive proximity sensor is actuated by conductive materials and is not responsive to nonconductive materials.
