hall effect sensor(ratiometric)

[hitesh joshi]

hi,
i am doing a project where i need to use a ratiometric hall sensor.i.e,when south pole of magnet is bought closer to sensor,sensor outputs a voltage applied and when the magnet is taken away,the voltage drops to zero or half of supply voltage..
i have been testing few sensors since a long time now..came up with WSH130.
anyone having any idea about other ratiometric hall sensors,which are easily available,kindly pl revert back.

thanks

Try A1302 Hall sensor. I using this sensor to measure contactless mains AC and DC currents. This sensor is direct replacement for UGN3503.

See one example for this sensor and magnet :
