Encoders are sensors that convert mechanical motion into electrical signals to represent position, displacement, rotation, or movement. They provide a structured output that can be interpreted by electronic systems for monitoring and control.
Within the sensor category, encoders are commonly grouped by their sensing and output method, such as:
- Incremental encoders, which indicate relative movement through a sequence of signal changes
- Absolute encoders, which provide a distinct output corresponding to a specific position
- Rotary encoders, designed to track angular motion
- Linear encoders, designed to track straight-line motion
As a component class, encoders are selected based on the required motion type and the preferred signal interface for integration into electronic control and measurement systems.
