Proximity switches or limit switches

[chillybo]

I used NPN normally closed proximity sensors in the end. I mounted them sideways on so they can't get damaged. They work a treat. I use them just as home switches. I have mounted some as limit switches but I haven't wired them up yet because soft limits seem to work just fine.

I'm debating my wiring for the NPN-NC prox sensors for mine too atm.
Easier to wire in series, however I have a UCBB with 18 inputs.
That's 1 for the estop, 6 for the servo, which leaves another 11 available.

Will be using CAT7 solid core shield cable to go from control box to a connector box on side of machine using RJ45 shielding connectors.
RJ45 modules at either end.
Then from connector box on machine side to the switches using flexible cable.

I have the CS labs IP/M controller that has plenty of inputs. I used the individual inputs rather than wiring in series.
