Potentiometers Line Guide Potentiometers convert rotary motion or linear displacement position measurement. Cermet and wirewound elements are into a change of resistance, supplying a smooth transition of stable over a range of operating temperatures and provide voltage or current levels. The resulting voltage output may be high power dissipation and improved resistance temperature used to control position transducers in a wide variety of potential coefficient. transportation, industrial and medical applications. Linear Potentiometers feature rugged extruded aluminum Rotary Potentiometers are compact, rugged, thick-film devices housings to withstand harsh chemicals and immersion in oils that use either conductive plastic, or cermet or wirewound or water. Construction features include extended life PTFE elements. Developed for potential military applications, our bearings, precious-metal multi-finger contact wipers, and MystR proprietary conductive plastic offers extensive temperature range conductive plastic thick-film elements. and infinite resolution, and is designed to provide precision FEATURES yielding consistent results. The PCB ROTARY POTENTIOMETERS profile, allowing use in a wide variety of containing the soldered devices may applications. Potential applications include be washed after soldering, saving time CONDUCTIVE PLASTIC use on audio and visual equipment, foot and yielding consistent results. Good POTENTIOMETERS pedal controls, machine controls, welding performance at a reasonable price.
