<p>PROBLEM TO BE SOLVED: To provide a proximity sensor system that has a longer detection distance without a change in size.SOLUTION: A proximity sensor system 100 for detecting proximity of a body A to be detected includes: a sensor unit 10 including an oscillation circuit section for forming a magnetic field at a predetermined oscillation frequency; and a detectable unit 50 attached to the body A to be detected and including a resonance circuit section having a resonance frequency based on the predetermined oscillation frequency. The oscillation circuit section comprises a detecting coil 21 and an oscillation circuit 25.</p> |
