Linear Potentiometers OPKON ERTM Series (Analog Output, 50–600 mm)

Linear Potentiometers OPKON ERTM Series (Analog Output, 50–600 mm)

Reliable Linear Position Transducers for Precision Measurement

Linear potentiometers are displacement transducers that convert the linear movement of a shaft (or rod) into an electrical signal representing its position.
These devices — also known as linear position sensors or potentiometric rulers — enable accurate position measurement of moving parts within a defined stroke range.

Their working principle is based on voltage division across a hybrid conductive film, ensuring high linearity and long-term operational stability.
OPKON ERTM potentiometers feature a rugged design, suitable for continuous industrial use, with multiple housing and mounting options to fit various applications.
