Magneto resistive linear position sensors and switches have a linear resistance output signal representing the distance an object is from a reference point

Linear position sensors, all types, is a general search form for all linear position / displacement detection product areas

Hall effect proximity sensors are used to detect the proximity, presence or absence of a magnetic object using a critical distance

Magnetic proximity sensors include devices that work on inductive, variable reluctance, magneto resistive or Hall effect principles.

Eddy current linear position sensors detect the distance from a target by using magnetic fields generated by a reference and sensing coils

Variable reluctance linear position sensors and switches are noncontact devices that use variable reluctance based technology, and whose output signal represents the distance between an object and a reference point

Linear variable differential transformer (LVDT) linear position sensors have a series of inductors in a hollow cylindrical shaft and a solid cylindrical core.
