Nexen® dancer position sensors are designed to accurately measure the rotational movement of a dancer arm. This family of sensors uses hall effect technology for infinite resolution, low drag and no mechanical wear. The DPS30A and DPS60A offer non-contact operation without the use of potentiometers or gearing. This means smooth operation (low drag), no maintenance and high accuracy. Its small size makes the DPS easy to install and incorporate into existing systems.
