Looking for recommendations - my customer has used Dynapar and is very unhappy. Looking for alternatives. Guidance?? Thx all

Perhaps an incremental encoder and a controller that simulate an absolute encoder? This can be very powerful and economic.

I've used Hengstler incremental encoders and was quite satisfied with them. Their web site does list at least one multi-turn absolute encoder model.

A big issue with encoders is to not exceed the bearing loads (damaged bearings) or the acceleration or vibration specs (damaged encoder disk). This isn't normally a problem when they are used on a servo motor (which is where most people see them). In other applications though, people are often not so careful. Whatever encoder you use, check the specs against the actual application environment.
