Sensata BEI’s MHM series of encoders is a shafted version while the MHK series is a blind shaft version. Both have 13 bits single turn resolution and 12 bits of turns. They can be electrically interfaced with either Ethernet/IP or Profitnet. Reverse polarity and short circuit protection are built-in. Lastly, turn counting is done through gears so it is immune to stray electromagnetic fields.
