产品描述

The MA710 detects the absolute angular position of a permanent magnet, typically a diametrically magnetized cylinder on a rotating shaft. Fast data acquisition and processing provide accurate angle measurement at speeds from 0 to 60,000 rpm.

The MA710 is particularly suitable for low magnetic field applications: side-shaft configuration or the use of non-rare earth magnets. 

The MA710 features magnetic field strength detection with programmable thresholds to allow sensing of the magnet position relative to the sensor for creation of functions such as the sensing of axial movements or for diagnostics.

On-chip non-volatile memory provides storage for configuration parameters, including the reference zero angle position, ABZ encoder settings, and magnetic field detection thresholds.

Long Eval Board for MA710

The TBMA710-Q-LT-01A is the long test board for the MagAlpha magnetic position sensor MA710. The sensor is mounted on the edge of the board and can therefore be used in both side-shaft and end-of-shaft configurations.

It requires the communications kit (EVKT-MACOM) and the Macom App Software (see below) to evaluate MagAlpha functionality and performance with your set-up, such as noise level, refresh rate, power-up time, and magnetic field dependence.

In addition to this long test board, there is a round format version (RD) where the sensor is mounted in the center of the board for end-of-shaft configurations

Round Eval Board for MA710

The TBMA710-Q-RD-01A is the round test board for the MagAlpha magnetic position sensor MA710. This configuration is used for end shaft sensing.

It requires the communications kit (EVKT-MACOM) and the Macom App Software (see below) to evaluate MagAlpha functionality and performance with your set-up, such as noise level, refresh rate, power-up time, and magnetic field dependence.

In addition to this round test board there is a long format version (LT) where the sensor is mounted on the edge of the board and can therefore be used in both side-shaft and end-of-shaft configurations.
