Can I test this without applying power?
It is a hall effect magnetic proximity sensor.
Here is the data sheet: http://www.datasheetarchive.com/preview/3528026.html I tried putting an ohm meter on it, but a moving a magnet around it doesn't make it change. |

I doubt it, the first page block diagram shows it has an internal amplifier which would need power to function. -- Clint Sharp |
