RM44 - up to 13 bit encoder base unit

RM44 - up to 13 bit encoder base unit

More Views

The RM44 encoder-sensor base unit is designed for integration on to electric motors or other devices for shaft position and velocity measurement. A Hall sensor ASIC is moulded into the solid metal housing to achieve the highest IP ratings, high EMC immunity, extended operating temperature range and the best possible shock and vibration resistance.

 

Available output options are 13 bit absolute SSI and/or 8192 cpr incremental. Many other options can also be provided including analogue sine/cosine, linear voltage as well as redundant functionality.

 

With the provided magnet a system accuracy of 0.2 degrees is achievable. A range of magnetic actuators for easy integration onto or into the shaft is also offered for easy system integration.
