Thru-Hollow Shaft Encoders - Reliable Potentiometer Alternatives

Thru-Hollow Shaft Absolute Encoders from FRABA POSITAL

Geared potentiometers are used in various applications where the positioning feedback of slow moving shafts is required. These potentiometers sometimes come with variable gear ratios to increase the number of revolutions they can measure. The mechanical complexity of these contact based potentiometric systems have drawbacks in terms of flexibility and reliability.
