The POSIROT® magnetic angle sensors of the PRAS/PRDS series are based on a contact-free and absolute measurement principle. The position sensing element is a permanent magnet.
The incremental encoders of the POSIROT® PMIS series consist of an MR sensor head and a magnetic ring as a magnetic scale. The encoders of the PRDS series use a permanent magnet as a sensing element.
The absolute POSIHALL® magnetic multiturn encoders measure angular positions over multiple revolutions using a noncontact magnetic measuring principle, which allows wear free operation.
The AWS angle sensors are using a high precision potentiometer as sensing device. Thanks to the specially designed output electronics, a high lifetime can be achieved.
