Default Sensor board's sensor replacement

Hi all,

is someone here ever changed bad sensors on sensor board ???
I want to make a test and the only thing is missing is a sensor.

I already know:

Supply voltage : 5VDC
SOT-23 case
Digital Latch Hall effect sensor type needed (What i suspect to be good, not sure)
Open Drain Output
High frequency banwidth
High magnetic sensitivity

If i'm in error or someone already has a part number , don't hesitate !!!

Thanks !!!

I just ordered the ones that looked dimensionally correct. Only one set of smd Hall effects for sale on ebay under rc cars. Mine are damaged and I ordered a complete replacement board and figure i could solder these on and if they worked they worked. They are the right voltage too.

5 bucks and nothing to lose. i have a solder station for smd so the work shouldnt be too bad either.

If you just visit Farnell you can select the product group, add some filters and all possible options pop out.

Visiting Farnell or mouser website is the easiest part of the job !!

There's a lot of sensor's type for those sensor : Omnipolar, Unipolar, Switch, Latch, Positive South, Positive North (Inverted). It's necessary to have the good type.

You also have to know the supply voltage, Output type, etc.

Not an easy task !!

You do need a latching hall sensor working on 5 max 6v (BEC voltage) and in this case a SOT23 housing

Open drain or open collector output is not realy needed.
