Thread: Uniport and limit switches.
Hey guys, im having a problem with wiring my limit switches up to the uniport.
Do any of you good guys have a wiring diagram which i could go off or possibly give me a fool proof option :whistling:
sorry maybe i should mention i would like the switches to act as home switches also. i had one test switch hooked up and homed the machine pressed the switch and it backed off but didnt stop until i let off the switch
I've been thinking about changing my limit switches, I'm very interested by RS pn: 171-3808, a slotted optical flag switch.
Here's a data sheet: http://docs-europe.electrocomponents...6b80028ba3.pdf
It switches with a max force of 1.5gms, they all agree with each other plus minus 3 degrees and it has a good overtravel (infinite if you get the actuator angles right).
What they don't tell you is the hysteresis and repeatability for an individual part. Even without the benefit of a Schmitt there is a distinct possibility it could be freakin' amazing as a positioning switch.
I will order some today and report back.

Wire them NC for safe operation then if a wire breaks or comes lose then the signals lost and machine stops.
The wiring is easy just wire them in series IE + - + - + - + -
cheers JAZZ, my switches only have 1,2,3 on them would 1 be the positive?
Do i have the right idea with this?
I got family not to far from there. Might see if they have counter service and get a group order together if they do as that looks like a very nice set up and with just a little bit of shielding from FOD would be a very dependable switch.
