Overview POSIROT®

Magnetic. Flexible. Suitable for outdoor use.

POSIROT® angle sensors detect angular positions of rotating elements with absolute precision by means of a magnetic measurement principle. They are resistant to impact, vibrations, and contamination, which makes them even suitable for use in harsh outdoor environments. Laser-welded, hermetically sealed, stainless-steel housing units guarantee a Long service life even in challenging environmental conditions (PRAS6), in hygiene applications (PRAS7), and in permanently underwater applications (PRAS4). POSIROT® angle sensors featuring degree of protection IP60 are suitable for demanding indoor aplications.

The functional principle

POSIROT® angle sensors rely on multihall technology to take contactless and wear-free rotation measurements. This involves a magnetic measuring element being secured to the rotating component so that the change in magnetic field during rotation can be measured by a multihall sensor. The sensor and magnet can either be integrated into a single housing or installed separately. The magnetic measurement method makes the sensor resistant to mechanical loads and contamination.
