Rodless slide linear position sensors have a piston connected to a carriage that rides outside the extruded wall, reducing overall length, making them ideal for small or tight location applications. Magnetostrictive and potentiometer sensors provide feedback based on cursor position.
Rodless slide linear position sensors, designed for applications where installation length is limited,
feature a cursor that rides within a channel along the top of the sensor housing to provide position feedback.
Linear potentiometers use a wiper that slides across a resistive element to provide resistance feedback;
they are a low-cost option, but wear out over time and must be replaced
Gefran magnetostrictive linear position sensors provide contactless position feedback and are not subject to mechanical wear
