Hi. I'm building a project with Hall effect sensors (flight sim rudder pedals) and in such project it was suggested to use SS495A sensors. Those are not as easy/cheap as A3144, which are the ones I got thinking I could use them instead.
However, they don't work as expected in the project, and when plugging those to an Arduino, looks like they have a very small voltage variance (in the range of the 200mV in the multimeter), so I suspect they have different characteristics. Is that likely to be the issue?
Possibly.
Original ( SS495a) are ratiometric.
These (A3144) are switches and are an open collector device so you will need a pullup resistor on the signal pin.
Best if you provide a circuit of what you have there.
The circuit is just left pin to VCC, center to ground and right to an Analog pin. No resistor requested, according to the project.
As I said, provide a circuit.
PLEASE draw a circuit, a picture of a drawing will be fine.
Can you please tell us your electronics, programming, arduino, hardware experience?
Thanks.. Tom.... 
Might be a good idea to provide the code as well.
I think you just answered my question there. I need an analog readout. If A3144 are switches, then they won't work. That's why I needed the SS495A as mentioned in the project files.
Thank you
