Inductive Proximity Switch: Recap

No. 1 Choice

So, what we've learned so far is this: If you can use an inductive prox switch to solve your application, do it. And what two conditions must exist to qualify? One, your target must be metal. And two, you've got to sense your metal target at close range. While that sounds restrictive, an enormous number of applications can be solved this way.

Recap:

They're relatively inexpensive, when compared to most other sensor types. They work fine in nasty environments. There isn't much to setting them up. They are immune to the variables like color and lighting that plague photo eyes. They're very fast and reliable.

Moving On:

Inductive proxmity sensors. They are the number one choice. Use them if you can. But if your target isn't metal, you can't use them.
If your target isn't metal, it's on to photoelectrics. Right? Well, not so fast. There is one more thing you might consider before choosing photoelectric sensors to solve your application.
