Position sensors are devices that detect the position of an object and convert that information into an electrical signal. They are commonly used in various applications, such as robotics, automotive systems, and industrial machinery, to monitor the location of moving parts. Examples of position sensors include potentiometers, encoders, and linear variable differential transformers (LVDTs). These sensors can provide information about linear or angular positions, helping systems to operate accurately and efficiently. By using position sensors, engineers can ensure that machines perform tasks correctly, enhancing safety and productivity in various industries.
