    I have a question: What happens when the magnets scarf up all the metal shavings and or plasma dust ? I have seen mag sensors used but it was on an engraving machine used for wood and plastic and the positions were covered I kinda like light instead of magnetism. Hall sensors are really good to sense current flow in a conductor.

    We're using them on routers, where this isn't an issue.

    Ya, sorry, I took the website down, it was costing me too much.

    I too have not heard from Romanlini or seen him around.

    Routers cut wood, plastic, aluminum, and brass. These tend not to be magnetic, so they don't stick to the magnets. The switches can be used for other things too, this design Romanlini came up with can be used for many things, for instance, hooking it to an Arduino based home made robot or something. Even 3D printer or laser etching/engraving machine.

    I had one of those cheap Chinese 40W laser engravers, and added these switches to it instead of those crappy micro switches they have, big improvement. Although I ended up selling the machine, as the extruded rails ended up warping. Those machines are so cheaply made.

    It's a fairly simply design, yet when configured correctly, can be extremely accurate for repeat-ability, as there are no moving mechanical parts.

    Hi
    Could someone help me with wiring these switches - I have the Honeywell SS451A's
    I'm easily confused and not electronically minded - a bad combination
    I have a HG08 breakout board from www.cnc4you.co.uk
    It provides 5V+ and five inputs. My understanding is
    1. connect the + tag to the 5v+ from the HG08
    2. connect the Out tag to one of the HG08's inputs

    I'm confused by:
    A. Where do I connect the middle (ground) tag?
    B. If I understand it right, these switches are Normally Open (with magnet absent) - does it not need to be Normally Closed, then when the magnetic field is present, Open?

    Spent all morning trying to work out what I'm sure is dead simple - if someone could help it would be appreciated.
    Data sheet for HG08 BOB is on www.cnc4you.co.uk website if that helps
    thanks in advance
    Joz

    Ok I've sorted it. Read through the earlier pages carefully, fitted the correct resistor, all sorted.
