Uniport and limit switches.

[Robin Hewitt]

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.

They do look interesting,!!
