Precision Pots

Precision Pots Bourns Industrial Electronics

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
