MSR 40 rotary position feedback system targets machine designers who want to measure angle on larger rotary axes. Suited for machines requiring motion feedback for full 360° or segment thereof, optical kit style encoder provides 200 micron grating pitch on steel tape that can be applied 3 ways to axis of motion. Available diameters range from 150–1,150 mm, and reader head is available with analog 1 V peak to peak interface as well as digital TTL interface with up to 100X interpolation.
