A position sensor is a sensor that detects an object's position. A position sensor may indicate the absolute position of the object (its location) or its relative position (displacement) in terms of linear travel, rotational angle or three-dimensional space. Common types of position sensors include the following: Capacitive displacement sensor
A linear encoder is a sensor, transducer or readhead paired with a scale that encodes position. The sensor reads the scale in order to convert the encoded position into an analog or digital signal, which can then be decoded into position by a digital readout (DRO) or motion controller. The encoder can be either incremental or absolute.
The position estimation results obtained by this set of formulae are simulated below. We assume the light spot is moving in steps in both directions and we plot position estimates on a 2-D plane. Thus a regular grid pattern should be obtained if the estimated position is perfectly linear with the true position.
Continuous sensor data transmission without interruption while using control data; Activation of actuators in bus during sensor data transmission; Broader standardization through BiSS profiles, BiSS EDS (electronic data sheet), BiSS USER DATA, etc. Full compatibility of BiSS identifier (already defined in BiSS B) [9]
Position sensors measure the position of a joint (the degree to which the joint is extended). They include: Encoder: a digital optical device that converts motion into a sequence of digital pulses. Potentiometer: a variable resistance device that expresses linear or angular displacements in terms of voltage.

A VR sensor used as a simple proximity sensor can determine the position of a mechanical link in a piece of industrial equipment. A crankshaft position sensor (in an automobile engine) is used to provide the angular position of the crankshaft to the engine control unit. The engine control unit can then calculate engine speed (angular velocity).
