Abstract
A sensor device for detecting a positional relationship between a first member and a second member, includes a first electrode provided on a surface of the first member and supplied with an alternating signal of a first frequency, a second electrode provided on a surface of the second member and supplied with an alternating signal of a second frequency, and a beat detector which detects a beat frequency component corresponding to a difference between the first and second frequencies indicative of the positional relationship between the first member and the second member, when the positional relationship between the first and second members changes to cause the first electrode to approach the second electrode.
