Thanks to confirm the programing need. So this sensor is not good option for DIY...
The so-called "MaRS" (МАРСЫ) is Russian circuit using magnetoresistive angle sensor (like these used in automotive industry). Advantages over ordinary HALL Sensor:
-good linearity sensitivity.
-dont need very strong magnets.
-if gimbal have metal structure this dont affect the sensor.
-whit trim pot you can adjust travel output angle.
This make more ease to install and adjust MaRS setups.
Due need of auxiliary amplifier circuit is more expensive than stand alone HALL sensor.
Sample of circuity:
Assembled "MaRS" sold by GLV224 from Ukrania (10 euros).
The blue thing is for adjust readable angle.
In term of resolution/precision no advantage from "MaRS" of HALL.
BTW- I dont experiment with these circuits - local market dont have all components, what I say is from lecture in simmers forums.
Commercial controllers that use "MaRS":
