Linear Motion Potentiometer PL2S

Excellent Linearity Stroke 50 mm to 500 mm     Infinite Resolution Two Ball Joints Conductive Plastic resistance element

Linear motion potentiometers series PL2S change mechanical linear motions into the corresponding electrical signals. Accurate, stout and reliable, they solve any problem linked to measuring and positioning control on any kind of industrial machine. Ball joints are provided at both ends for air fixing, which allows to compensate slight mis-alignments in the application.

More Features:

Moving speed up to 1 m/s

Shaft diameter mm

stout aluminium case

easy clamping by movable feet or ball joints

electrical connections by orientable connector

 IP65 protection
