[TowerTalk] P3020-V1-CW360 - Hall sensor

[HA3LN <list@ha3ln.hu>]

Dear Members,

Does anyone know/use any of these 2x type of Hall sensors?

P3020-V1-CW360
P3022-V1-CW360

(pics and short video clips about the problem)

I'm about to renew my old rotator system with an Arduino based 
controller where the azimuth sensor meant to be this Hall sensor.
Gives 5Volts output which is greatly matches to the Arduino analog input 
levels.
These sensors are advertised like 360 degree with "no dead angle" but it 
seems there are ~45 degrees where no change in output voltage is visible.
So the full 360deg rotation is mapped into ~315 degrees.


I'm wondering whether is this the proper operation and my interpretation 
of "360 no dead angle" fools me?
I don't see any option to calibrate on the housing. I have 3-3 pieces of 
each types and all 6 works similarly.

Thanks.

73!
