Simple Tips for Encoder Repair and Troubleshooting

If motion control is important to your production, then your encoder is one of the keys to your success. Encoders are exposed to shock, contaminants/oil, excess vibration, moisture, and high temperatures that regularly put their toughness to the test.

There are a lot of encoders out there in industry, doing their job 24/7. These little workhorses includ incremental aka quadrature encoders which uses a transparent disk with section equally spaced to determine movement; absolute encoders which use a photodetector and LED light source and a disk with concentric circle patterns; linear repairs for linear encoders which  use a transducer or reading-head linked to a scale; magnetic rotary encoders which use hall effect sensors; and commutation encoders which are similar to incremental encoders but have commutation tracks along the outer edge of the disk.

Choosing Which Encoder to Buy

First, start out right! Two basic rules apply to buying encoders:
