Compact angle sensor for wear-free rotation detection

The posirot® PRAS20 offers precise angle measurement, especially for tight installation spaces

Magnetic. Wear-free. Flexible. That is the posirot® PRAS20 from ASM. The angle sensor is suitable for applications such as operating tables, doors, opening valves, packaging or printing machines. Even tight installation spaces are no problem for the sensor in a 6 mm flat housing. A redundant version, posirot® PRAS 20R, is available.

posirot® sensors use multihall technology for non-contact rotation measurement. A magnetic measuring body is attached to the rotating component for measurement. The change in the magnetic field during rotation is measured by a multihall sensor. This magnetic measuring method means that the sensor is wear-free.

The posirot® PRAS20 has a measuring range of 0° to 360°. The linearity is ± 0.5 % and it has protection class IP60.
