Precision Pots Multiturn
   

Precision potentiometers are designed for control applications where accuracy and high-reliability is important. These devices are available in conductive plastic, wirewound or Hybritron® element types, and in various sizes. Both single-turn and multiturn models are available. Typical applications include measuring linear distance, angles or rotations in production equipment, industrial test and measurement equipment, and medical equipment.

 
Products marked with this symbol are currently available, although not recommended for new designs.
