Hall effect proximity sensors
I'm thinking of using these for homing sensors as they have a longer sensing range than the standard proximity sensors which I'm using for limits.Just wondering if anyone had experience of them and what the accuracy was like please.

Duh Link???
Re: Hall effect proximity sensors
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 ?

"These" referred to the title of the thread.......

Ahh
Ok I got it.

But I personally would stick to Inductive sensors.
Re: Hall effect proximity sensors
2 inductive sensors in series on each axis, one sensing the linear position and one sensing a rotating tab or chopper on the ball screw or stepper would give you accurate, repeatable homing.

Having a rotating tab on the ballscrew is a good idea - essentially magnifies the resolution - I'll see if there's room to incorporate it.

I presume these would have to be the Normally Open types. I think it is over the top for woodwork, but probably OK for watchmaking.
