Hall effect

Hallo!

Can someone tell me how close you can put hall effect sensors to each other and still detect witch sensor switches the magnet is placed above.
Or in other words... Hall switches on a straight line, with some magnets just above. How close can I put the sensors without having the sensors next to one with a magnet jumping between high and low.

I hope it us possible to say something in general about this issue. And further more if someone have specific experiences with the sonword i have ordered:

OH137 TO-92S Hall Effect Sensor Switch Circuit for Highly Sensitive Instruments Hall Senso

I could not find information about this, but thanks for a nice forum with valuable information.

Depends on the magnet u’ll be using! Use a magnet <3mm diameter.
The sensors can be mounted side_by_side , 4.5mm (the sensor is 4.1mm )
