PT8420 Series

The PT8420 Series from TE Connectivity is a family of cable-extension linear position transducers, also known as cable-actuated position sensors. These devices convert linear displacement into an electrical signal using a spring-retracted cable connected to an internal potentiometer, delivering continuous position feedback via a 4-20 mA current output proportional to cable extension.

Available in a range of measurement lengths spanning from around 10 inches up to 150 inches and beyond, the series suits applications requiring precise linear displacement measurement. Common end uses include paper manufacturing, web processing, and material handling equipment.
