Replace magnetic sensor - help identify 3-pin IC marked "W10" and "1095"
I've found these guys being sold:

Hall switch EW510 Asahi into Hall component W10 treadmill speed
control brand with Hall ew510.

They have the W10 marking. If EW510 is really your W10 component, then here is it's datasheet.
It doesn't seem like a very easy component to buy, so maybe you could use the datasheet to guide you into buying another hall effect sensor IC with compatible characteristics.
