The SR33/34 Ultra-Magnescale has the world's smallest magnetic encoder signal period of 40µm providing low distortion 40µm sine waves 1V p-p and A/B quadrature resolution to 0.05µm. The new unique technologies used in the scale bring the combination of robust magnetic scale reliability, high accuracy and fast speed with complete referencing options including distance coded reference marks.   The scales dimensions and installation method provide close compatibility with other popular optical feedback linear encoders reducing the need for OEM to make design changes on new machines and providing alternative service replacements for machines in the field.   The SR33 model provides direct 1Vp-p signals, the SR34 direct A/B quadrature 0.1µm resolution and the SR33 combined with cable assembly CN33 has switchable A/B resolutions of 0.05, 0.1, 0.5 and 1µm.
