Position Transducers
This section presents a sample of our linear position transducers.  Our products utilize two technologies, MystRŪ conductive plastic and wire-wound.  Conductive plastic potentiometric sensors are long-life units designed for rugged industrial applications.  Our wire-wound products continue to serve in applications where current is being drawn through the wiper is necessary.

The following guide should allow you to quickly compare the major characteristics of each transducer.  For more detailed information on any transducer refer to the product section.  Don't forget to see our section on how to select a position transducer if you are not sure what transducer will work best in your application. It's a step-by-step analysis of the factors you need to consider before buying a transducer.

What You Should Know About Our Position Transducers
The Honeywell Sensing and Control Transducer products group manufactures a variety of potentiometric position sensors in its Massachusetts plant.  The sensors use a tried and true potentiometric technology originally developed for military applications and more recently applied to industrial markets.  The proprietary MystRŪ conductive plastic has extensive temperature and power capabilities along with infinite resolution in very small stroke units (5 mm [0.2 in]) without any intermediate signal conditioning.  In a world where miniaturization drives sensor development, potentiometers have shrunk to the point where their weight is measured in grams and their stroke in millimetres.  This amazing technology can still be utilized for measurements in tens of feet with repeatability in thousandths of an inch.

The old belief that potentiometers are reliable but short-lived is giving way to the understanding that new potentiometer technology combined with creative mechanical designs has substantially reduced the element and wiper from the unit's life calculation.  It is now the bearings and other components, which must be studied to determine the unit's life.  We now talk of billions of operations where a few years ago we talked in millions.  In many cases the life of the potentiometer is longer than the life of the unit it is monitoring.

Wire Wound products are also available to serve your needs when current is being drawn through the wiper.  These products may be a variable resistor or semi-precision Potentiometer.  The Honeywell Position Transducer Products Group now manufacture the Wire Wound products formerly manufactured under the "Waters" name.  Our JP/2, PT 3/4 and WPM 7/8 product lines, qualified to various MIL Specs, continue to serve in limited life and high reliability applications.  We manufacture many thousands of JP/2's, for use in dimmer controls for aircraft panel lighting, annually in our Acton location.
