Encoders are widely used in:
An optical encoder uses light-based technology to detect movement.
Inside an optical encoder, a coded disc rotates between a light source and a sensor. As the disc moves, the sensor detects changes in light patterns and converts them into electrical signals.
Optical encoders are known for:
They are commonly used in applications where extremely accurate motion control is required.
Typical applications include:
However, optical systems may be more sensitive to contamination such as dust, oil, and moisture because their sensing method depends on light transmission.
A magnetic encoder uses magnetic fields to detect position changes.
Instead of using a light source and optical disc, magnetic encoders use magnets and magnetic sensors such as Hall-effect sensors or magnetoresistive sensors.
Magnetic encoders provide:
Because of their rugged design, magnetic encoders are suitable for harsh industrial environments.
