The RE58 is a modular bearing\/shaft encoder system that has been designed for easy integration to existing 58 mm synchro flange and clamp applications.","The modular design combines the benefits of the non-contact OnAxis™ magnetic encoder technology with existing industrial encoder designs. The non-contact RM44 encoder used on the back of the bearing\/shaft assembly provides ultimate reliability in harsh environmental conditions where other encoders would fail. Even if the bearing\/shaft fails it can be easily replaced without damaging the RM44 encoder. The RM44 encoder offers a wide range of output options including incremental, absolute and analogue protocols with up to 13 bit (8192 counts per revolution) resolution.
