Customizable CNC Electronic Edge Finder for Professional CNC Manufacturing Needs

You're looking at roughly $45 for a single sample unit, dropping to around $38 each if you grab 5-10, and under $30 when you're buying 50 or more—that's the kind of pricing that makes sense when you're running a shop that burns through these things. We usually have stock, but confirm lead time if you need more than 100 pieces at once.

It basically works like a photoelectric contact probe with a buzzer, so you get a clear audio or visual signal when it touches your workpiece—no guessing, no accidental crashes—and the whole thing runs on standdard 12V DC power. Most buyers go with the metric version for new CNC mills, but the inch model is available if you're working with older equiment or imperial tooling.

The body's made from decent steel, not some cheap alloy that'll snap after fifty uses, and the precision is quoted at 0.001mm which is better than most for general mill setup work. Don't use this for coolant-heavy environments though—it's only rated IP40, so splashing it directly with flood coolant will shorten its life.

What it does is let you zero your workpiece edges stupidly fast without spending five minutes rocking a manual edge finder back and forth—just touch, hear beep, zero your axis, and you're done. The thing is 100,000 operations or so, which is plenty for a small job shop that might use it a dozen times a day.

You get it as a single piece, no collet or holder included, so make sure you've got an ER collet setup handy—that's something buyers don't always think to ask about. The lead time runs 7 to 20 days depending on whether we've got a batch queued up, and customiztion (different voltages, custom cable length) is actually possible within reason.
