It's a neodymium magnet. I made sure that I had it the right way round. I'll try a bigger one tomorrow. |
| John Hill:
If you have another the same just stick it on top of that one.. |
| NormanV:
That's what I was planning to do, if it works then I will glue it to ensure that it doesn't move. |

Norman, All the proximity sensors that I've used (and that's quite a few!) don't need a magnet to operate. The sensor senses the iron presumably using it's own magnetic field. So for instance you can bring one up close to the teeth of a gear wheel and sense each tooth. Try removing your magnet and sensing the hole where it was - I suspect the strong magnet that you are using is stopping the proximity sensor working. |
| Arbalist:
Good info Andrew. :thumbup: |
