I've used a bunch of Keyence ones. They work good but are $$$.

Been searching Google and have not found much so far. I was wondering if someone had a known good supplier on a decent proxy switch. I have seen them from a couple bucks each to 100's, and not really sure what most people are using. I think I want to go with the inductance type. Anyone have any experience with them? Once I get it figured out I will try to write up a schematic to share of how I got it all working.

I used the mechanical Microswitch kind for about 3 years now, they work fine. Decent repeatability.
On my new machine i bought 4 of these: eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices
I think they are going to work better than the mechanical style, only time will tell.
I was going to build the Hall effect switches from the "home switches made easy" thread, but I had trouble finding the proper parts and didnt feel like making a housing for them. The ebay ones were a good tradeoff.
Automation Direct sell Proximity switches pretty cheap.

I use automation direct stuff all the time, good products and good prices. Expect to pay about $18.00 each. If you are feeling really crafty you could do what I did. Purchase hall effect sensors (5 pack on ebay for $7) and make your own sensors. These tiny sensors are hard to mount but after soldering the wires on I put them in a brass tube and filled them with epoxy. Now they are easy to mount, add a small magnet and you have a very accurate solid state sensor. I have three of these on my machine.

These ones are all over Ebay. New LJ12A3-4-Z/BX Inductive Proximity Sensor Switch NPN DC6-36V | eBay
If they work properly, then it does not get much better than that.
I can never figure out how they can include shipping from Hong Kong on items like this?

Darn, thats a great price. wish I had seen those, although they require a different mounting method than the ones im using. So cheap..Originally Posted by LazyMan
Those might just be what I'm looking for assuming they are accurate enough. For $12 I can get the 3 needed for my machine shipped....? It's worth a try! Worst case they can be used for a limit switch later on another machine.
If you try them out let us know how well they work.
