The inductive displacement sensor includes a first element of cursor (31) and a second element or scale (32) exhibiting spatially periodic electromagnetic characteristics, such as windows (321) and traverses (322). The first element (31) has a series of windings, e.g., three interlaced meander windings (31A to 31C) and an electronic circuit being connected to the windings on the first element to bring about a current in at least one of the windings (31A) and to measure the influence due to the position of the second element's spatially periodic electromagnetic characteristics on the inductances of at least a part of the windings (31B, 31C) of the first element (31). Such a displacement sensor is simple, rugged, small, draws little current and is insensitive to water.
