RSF Elektronik Linear motion feedback encoders
RSF Elektronik’s MSA 37x series linear motion feedback encoders feature a design that includes a bearing set internally for guiding the scanning optics and a bearing set externally for attaching a coupling rod that affixes to the machine, thereby allowing the moving elements of the machine to be measured. Digital TTL resolutions of 5 and 1 micron are possible, with accuracies up to +/- 10 micron. The encoders also have magnetic limit switches that can be used to send end-of-travel signals to the control. Reference marks can be in the center, on either end of travel or every 50 mm.
