ABSTRACT:
The disclosed displacement detector uses a printed circuit board extending through a comparatively uniformly magnetized gap of a core. The core is essentially a closed loop of magnetic material enclosing a hollow space, and a magnetic material leg extends from a portion of the loop to the hollow space so as to define the above-mentioned gap between the extended end of the leg and a side of the loop facing therewith. A first coil is wound on the leg of the core. The printed circuit board has a second coil with a plurality of mutually spaced turns with slant portions, so that linkage of the magnetic flux of the core gap with the second coil varies depending on the relative displacement between the core and the printed circuit board. The slant portion of the second coil can be made symmetrical with respect to a center line parallel to the relative movement between the core and the printed circuit board.
