An inductive sensor (1) detects the position of a detection object with respect to a fixed body (6), the detection object being a rotating body (7) provided so as to be rotatable about a predetermined axial center with respect to the fixed body (6), or a movable body (8) operating in conjunction with the movement of the rotating body (7). An inductive sensor (1) is provided with circuit boards (10, 11, 12) and a plurality of targets (20, 21, 22). The circuit boards (10, 11, 12) are provided with transmission and reception coils (30, 31, 32) including a transmission coil and a reception coil, and a transmission and reception circuit (35) which supplies high frequency to the transmission coil and outputs a signal corresponding to a change in inductance of the reception coil, and are fixed to the fixed body (6). The plurality of targets (20) operate in synchronization with the movement of the detection target, and are configured to include a conductor (25).
电感式传感器(1)将相对于固定体(6)以能够绕规定的轴心进行旋转的方式设置的旋转体(7)或者伴随该旋转体(7)的运动而动作的可动体(8)作为检测对象,检测检测对象相对于固定体(7)的位置。电感式传感器(1)具备电路基板(10、11、12)和多个靶标(20、21、22)。电路基板(10、11、12)安装有包含发送线圈及接收线圈的收发线圈(30、31、32)和向发送线圈供给高频且输出与接收线圈的电感的变化对应的信号的收发电路(35),且固定于固定体(6)。多个靶标(20)与检测对象的运动同步地动作,且构成为包含导电体(25)。
