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

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

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

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

Inductive linear position sensors and switches are noncontact devices that determine an object's coordinates (linear or angular) with respect to a reference

Linear position sensors and switches, ultrasonic, are used for position and displacement sensing, using ultrasonic technology
