Answer:D
What is the difference between a NO and NC proximity switches?
A. The threshold for detecting objects is different B. The sensitivity of the sensor is different C. The orientation of the sensor is different D. The state of the output when no object is detected is different
Explanation: The main difference between a normally open (NO) and normally closed (NC) proximity switch is the state of the output when no object is detected. A normally open switch will have an open circuit when no object is detected, while a normally closed switch will have a closed circuit when no object is detected.
