Renishaw’s SR readhead and Si interface are part of the new range of encoders.
They have been designed for use with Renishaw’s range of RESM angle encoders which incorporate the IN-TRAC TM
bi-directional reference mark.
Like all Renishaw encoders, the
range offers high speed, reliable operation and open, non-contact performance with excellent immunity to dirt and electrical noise.
The interface incorporates dynamic signal control which, combined with the patented
fi ltering optics ensure excellent signal integrity and low cyclic error.
The Si interface can be mounted remotely and a small connector on the readhead cable allows it to be fed easily through machines where access is restricted.Readhead (s R)

Note: IN-TRAC TM reference mark is integrated in the scale and does not require any external magnetic actuators or physical adjustment. For applications such as partial arc, dual on-scale limits can be used on ‘A’ section rings having an external diameter of 100 mm or more.
Maximum speed (m/s)
Speeds quoted in m/s. Angular speed depends on ring diameter - use the following equation to convert to rev/min.
Angular speed (rev/min) = V x 1000 x 60
π D Where V = maximum linear speed (m/s) and D = external diameter of RESM (mm)
