The sensors are suited for mobile, harsh environments, and limited-space applications. Noncontact technology with rotating shaft is found in RSC-1300, 2200, 2800, and 3700 series. Touchless technology with no shaft and featuring a round position marker that mounts separately at a distance from the detecting sensor component is featured in the Vert-x E and RFC series sensors. The sensors extend from 13 to 48 mm in diameter. Specifications include programmable angular range to 360, resolution to 14 bits, and up to unlimited mechanical life.
