RESR and SiGNUM™ Optical Angle Encoders from Renishaw. Renishaw's high accuracy angle encoders are available in a large range of diameters and line counts to provide compatibility with standard controllers. Based on a one-piece stainless steel ring with axial graduations marked directly onto the periphery. Available in both standard or low inertia sections to suit a diverse range of applications.

The RESM and RESR angle encoders feature a large internal diameter, giving them an ultra-low section and a very low moment of inertia. This means that whenever they are installed, the rotor can be positioned with minimal torque and maximum speed.
In addition, the large internal diameter provides somewhere convenient to feed all the necessary cables and pneumatic supplies making integration easier than ever.
Do not be misled by the slim cross section - it does not compromise accuracy. In fact, Renishaw's patented taper mount compensates all installation tolerances, including those of the parent mounting surface. Eccentricity and ovality are also corrected by easy, robust and fine adjustment.
