A simple hole or sticking out bolt head will do fine. --- End quote --- Yes, quite right. Normans was a proximity sensor so no magnet required. In fact when he tried a magnet it didn't work. :D |
| John Rudd:
Well whatever it is, so long as Norman has it working thats all that matters here...., But, the ebay link he provided links to a display with Hall sensor, thats what the descriptions reads, bur then the seller could be wrong.... |
| awemawson:
Mine is like the original link and is a PROXIMITY sensor. The central core is a magnet with a coil wrapped around it, and it has internal electronics to detect the flux changes in the coil created by external magnetically susceptible material passing close by |
| John Rudd:
Ahh.... The light has come on! Got confused by the op and the thread by Norman.... :doh: Ermmm.....I'll dip out on this.... |
