Linear Potentiometers

AutomationDirect now offers eight series of GEFRAN linear potentiometers and accessories. Configuration styles include slide housing, heavy duty cylinder with rod eyes, rodless slide, spring loaded with ball tip, 1/2inch diameter cylinder with flange, rod eye or bracket mounting and 3/4inch cylinder with rod eye mounting. Stroke lengths vary from 10 to 1000mm depending on the series. Linear potentiometers are used to detect position and linear direction movement. A sliding contact moves along a linear resistive element acting as a variable resistor. The proportional change in resistance indicates the position and provides a distance measurement signal. A signal conditioner can be used with the potentiometers to convert the signal to 0-10V or 4-20mA.
