MPS MA732 magnetic sensor


Angular Sensor for Position Control, 8 - 14 bit Adjustable Filter, ABZ & SPI

The MagAlpha MA732 features programmable digital filter bandwidths and ABZ interface hysteresis settings so that the user can optimise the sensor to meet the dynamic response needs of different types of control loop. Loop response time can be traded against angle resolution, start up time and ABZ pulse count to match different system types. An example application could be to support a higher ABZ pulse count of up to 1024 pulses per channel compared to the 256 found in the MA702. Example MA732 applications include position or speed encoders in brushless DC servo motor or actuators.

Accurate angle sensing at speeds from 0 to 60k RPM is supported. SPI, SSI, ABZ and PWM interfaces are provided. End and side-shaft magnet topology is supported.
