The RESR and SiGNUM RESM angle encoders feature a ±5 arc second scale graduated axially onto a stainless-steel ring. Available in a range of 20 diameters (from Ø52 mm to Ø550 mm), Renishaw's angle encoders have a low cross-section and a large internal diameter to position easily around large internal rotors, payloads or services.
The rings also feature a unique taper mount which corrects for eccentricity of the rotor/shaft and ensures excellent accuracy, offering easy and robust fine adjustment of the ring's form and all installation tolerances. In addition, the rings offer a very low moment of inertia ensuring that whatever the installation, the system can be positioned with minimal torque and maximum speed.
