Linear encoders are devices used to measure the position of an object along a straight line. They work by converting the physical movement of an object into an electrical signal, which can then be interpreted by a control system. This technology is commonly used in machinery, robotics, and automation to ensure precise movement and positioning. There are two main types of linear encoders: incremental encoders and absolute encoders. Incremental encoders track movement by counting steps from a reference point, while absolute encoders provide a unique position value at all times. Both types are essential for applications requiring accurate and reliable position feedback.
