Embodiment Construction
[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0030] like image 3 As shown, the inductive proximity switch sensor of the present invention includes an excitation circuit unit 1, a coil detection circuit unit 2, a signal processing circuit unit 3, and a detection coil unit 4 arranged toward the detected object 5. The detection coil unit 4 includes movement along the sensor. Two or more detection coils 41 are arranged in sequence. The detection coils 41 are flat rectangular coils arranged in sequence and attached to the non-metallic plane. The length of the detection coils 41 is greater than the shortest length of the detected object 5 . The width of the detection coil 41 is greater than or equal to one-half of the maximum width of the detected object 5. The excitation power supply unit 1 is connected to the detection coil unit 4 and the adjacent detection coils 41 are connected wit...
