A magnetic linear position detector includes a stator and a mover that is movable along a first direction with respect to the stator. One of the stator and the mover is provided with a magnetic detector. The other of the stator and the mover is provided with a magnet having a first face facing the magnetic detector. The first face is magnetized in such a manner that a magnetization direction changes in an arc shape around a magnetization center point. The magnetic detector is an element whose output changes depending on a direction of a magnetic field.

A pulley serving as a rotary body and a scale configured to rotate integrally with the pulley are attached to an end portion of the pulley serving as the rotary body in a thrust direction, a detection unit is configured to detect rotation of the pulley serving as the rotary body by reading a reading region of the scale. An absorber capable of absorbing liquid is attached to a surface of the scale on which a reading region is present, and when liquid adheres to the scale, the absorber absorbs the liquid.

An inductive position determination device, in particular an inductive angular position determination device, for determining a position and/or a movement of a movably supported drive component includes: the drive component which is formed from at least substantially at least electrically nonconductive materials, and an encoder element which is in particular integrated at least into the drive component and/or fastened on the drive component, which moves along with a movement of the drive component and which is formed from a metallic, at least substantially nonmagnetic and at least substantially electrically conductive material, wherein the encoder element is configured for interacting with a sensor module for the purpose of position determination, and wherein a density of the material of the encoder element is substantially greater than an, in particular average, density of the drive component.

An inductive position sensor is disclosed. The inductive position sensor can include a substrate having inductive sensing coils. The inductive sensing coils can be disposed on or at least partially embedded in the substrate. One or more processors can be configured to process an output signal and determine a distance based at least in part on the processed output signal electrically connected to the one or more inductive sensing coils. The processors can control and manage an input signal and an output signal. The one or more processors can be configured to determine a position of a target. The target can comprise an electrically conductive moving target configured for tracking an object for measuring a position of the target. The substrate can be a flexible substrate that is non-planar and conforms to a surface profile of the target.
