MSR 40 modular rotary position feedback system from RSF Elektronik is for machine designers that want a quick way to measure angle on larger rotary axes. The device's optical kit style encoder provides a 200 micron grating pitch on a steel tape that has three ways of being applied to the axis of motion. The unit is suitable for machines that require motion feedback up to and including a full 360°. The same reader head can be used for the different diameters offered, and is available with analog 1 V peak-to-peak interface, as well as digital TTL interface with up to one hundred times interpolation.
