Abstract

A proximity sensor includes a transmission circuit that supplies a current to each of detection coils, a reception circuit that detects voltages generated at both ends of the coils or currents flowing in the coils due to the supply of the current for each of the coils, a control unit that senses the presence or position of a detection object using a detection result of the reception circuit, and an output unit that outputs a sensing result of the control unit. The control unit extracts a first component caused by a mounting fitting for mounting the proximity sensor on a support member and a second component caused by the detection object from the detection result of the reception circuit. The control unit compensates the second component using the first component. The control unit senses the presence or position of the detection object on the basis of the compensated second component.
