3.Description
• SME200 is used for magnetic off-axis position definition with integrated Hall sensors. By scanning two separate channels the device can log an absolute position. The chip conditions the sensor signals and compensates for typical signal errors.
• The internal 12-bit sine/digital converters generate two position words that supply high-precision position data within one sine-period.
• The integrated Nonius calculation engine calculates the absolute position within one mechanical revolution and synchronizes this with the master track position word. Position data can be transmitted serially, incrementally, or analog through two ports in various modes of operation.
