firstmarkcontrols 162H Miniature Position Transducers  Technology Overview
String Pots (also known as cable actuated position transducers, draw wire sensors, string potentiometers, and yoyo pots) convert mechanical motion into an electrical signal that may be metered, recorded, or transmitted. Firstmark Controls string position transducers consist of a stainless steel displacement cable wound on a threaded drum that is directly coupled to a precision, long-life sensor. Operationally, the transducer is mounted in a fixed position and the extension cable is attached to a moving object. As movement occurs, the displacement cable extracts then later retracts under the power of an internal, engineered spring which also maintains tension on the displacement cable throughout its stroke. The rotation of the sensor produces an electrical output proportional to the displacement cable giving indication of positional translation.
