Data sheet RLMD01_09 Issue 9, 14th February 2020 RoLinTM miniature packaged incremental magnetic encoder sensor system RoLinTM is a component level encoder consisting of a RLM readhead and a magnetic scale or ring. It has been designed for embedded motion control applications as a position control loop element. communication protocol is selected the value of internal period counter (1 pole = 1 period) can be output. 8 bit, 12 bit or 24 bit counter lengths can be selected. Optionally, period counter can be reset when traversing the reference mark (if selected). Position information is output in incremental quadrature and parallel, SSI or BiSS format with the option of a periodic reference mark (every pole). When SSI or BiSS failures of the encoder which are signalled on the Error line using a PWM formatted code. ●● Incremental ABZ, TTL or RS422 logic level ●● SSI or BiSS, TTL logic level ●● High speed operation ●● Bidirectional reference mark ●● High reliability from proven nonMaximum speed depends on the contact sensing technology chosen resolution and minimum edge separation time; e.g. for linear ●● Pin / Flex cable options The information carrier is applications to 7 m/s at 1 µm and ●● Self-diagnosis feature a periodically magnetised scale with to 75 m/s at 10 μm.
