POTENTIOMETER SELECTION BY APPLICATION
In the Past 30 Years Designers Have Drastically Increased the Performance Requirements of Potentiometers.
Spectra Symbol Has Innovated to Meet the Demand.
Linear, Rotary, or Flex Form Factor
When deciding the component that is best for your application, you likely already know the form-factor that will be required. We have potentiometers that fit virtually any mechanical action.
A Potentiometer as a Position Sensor
When used as a position sensor, tracking linearities of as low as 0.5% can be achieved. Or even lower with supporting calibration circuitry.
A Potentiometer as a Control Component
When used as a control, output can achieve the same accuracy as when used as a position sensor.
A Potentiometer as an Output or Input Trimmer
When used as a trimmer, our potentiometers allow for extremely precise manual or automated adjustment or limitation of an in-circuit value. This is used less frequently these days as with conversion into digital designs, trimmers are being replaced in some cases by digital tuning devices that store values electronically. However, these digital circuit designs still needed an input to control the system. Potentiometers have evolved to become the preferred low-cost variable-input device.
