Magnetic sensing technology is best for operations in very high temperatures and environments with extreme shock and vibration. Magnetic encoders tend to have fewer resolution options and lower precision than their optical counterparts and can be more susceptible to environmental magnetic interference. Ideal applications for magnetic encoders include wind energy, tree harvesting, traction motors for rail equipment and pavement profiling.

Incremental Magnetic Encoders

This type of encoder provides information about the instantaneous position of a rotating shaft. The encoder does this by producing one square wave cycle per increment of shaft movement. Incremental output is ideal for applications where relative movement is desired.

Absolute Single-Turn Magnetic Encoders

This type of encoder provides a unique binary word for each position. Ideal for applications where a device moves at a slow rate under one rotation or is inactive for long periods of time.

Absolute Multi-Turn Magnetic Encoders

Similar to absolute single turn encoders, however they are ideal for applications where a device moves at a slow rate with multiple rotations or is inactive for long periods of time.
