Hall effect proximity sensors

[the great waldo]

I was just asking for general advice rather than for a specific device - but likely something like the NJK-5001C

Hi Voicecoil
I'm not sure if you checked your original post but you wrote "I'm thinking of using these for homing sensors" however "these" didn`t refer to anything, so a sensible reply would have been difficult. Maybe this was just a typo ?
