The CLP21 series is used in applications where a
robust and compact displacement sensor is required.
Linear potentiometer (conductive plastic) with almost
innite resolution
Measuring lengths from 15 mm to 100 mm
Compact dimensions
Long lifetime (up to 40 million movements)
With and without spring return
This compact displacement sensor with robust aluminium
housing oers many options and covers a wide range of
applications. The sensor can be mounted with clamps or by
thread holes.
*Note: Spring return versions in IP54 have an operating temperature range of 0..+60 °C
