Look at this thing! Built with love by our own Jessi Bratcher in the Dallas UL508A Panel Shop. Great job, Jessi, keeping it Legendary for our panel customers.
Our scale of operation and shop efficiencies mean we many times can build panels in less time and for less cost than our customers can do for themselves. We can build to your prints, or help you design your control panel. Try us!
Hi, I’m Adam Ring with Innovative-IDM. You know, when I walk through manufacturing plants, sometimes I’ll come across a control panel where you open it up and look inside and you see this technology that is like 30, 40 years old. So what’s starting to happen is, customers are finding that a lot of the controls in their automation are starting to really become aged, and when that happens if something breaks it's really, really hard to find.
We find a lot of people who try and search on eBay to find replacement parts. Sometimes they’ll send them in and try to get parts repaired. But as they continue to age, the repair gets more and more expensive and eventually things just get to the point where they’re not repairable anymore. One of the worst things that happens is a major component necessary for the operation of a machine goes out and then the machine is completely rendered useless until you either find a new part or completely rebuild the controls for it. And so by retrofitting a control panel, you’re able to remove any of those obsolete components and replace them with the current up-to-date stuff that’s readily available. It gets rid of all of your hard to find really difficult parts, it enables you to not have to worry about repairs for a while.
Typically the life of a new control panel, before you have to really start repairing stuff, usually lasts about 10 years before it starts to break down and then you eliminate that big terrible major risk of down time. And everyone knows, whatever the cost to build a new control panel is usually minimal in regards to or compared to what it costs if a machine goes down or can’t produce products for weeks or months on end while a new control panel is being designed and built.
So overall, it’s a really good idea if you’ve got aged control panels where a component going out could really, really cost some major downtime and production loss, it’s a good idea to go ahead and take a look at retrofitting those control panels.

Hi, Adam Ring with Innovative-IDM. I wanted to take a few minutes and talk about the battle between the screw terminal and the cage clamp. So, why do people choose one or the other? Well, let’s just look at some of the basic facts. On the screw terminal, when you strip a wire and insert it into a screw terminal, the tightest that that’s ever going to be is the connection at the time you actually torque that screw driver down. From that point on it’s only ever going to get looser. Now when you talk about cage clamp terminal, when you strip the wire and insert it into the cage clamp, that’s actually the loosest that connection ever is. And as that wire then starts to take the shape of the terminal and the wires kind of splay out and basically mold to the shape of the terminal, it’s actually going to get tighter over time because of the spring force that’s holding that wire in place.
So, with temperature cycling as that wire has current running through it and it heats up and cools down and heats up and cools down, it’s going to be expanding and contracting and so forth. Well with the screw terminal, that’s only going to force that screw to back out and get looser and looser over time, whereas with the cage clamp with its spring technology, the spring actually compensates. As the wire expands, it expands, when the wire shrinks back it shrinks back with it and so it always maintains the right amount of tension on the wire for the application.
Now there’s also industrial applications; there’s typically a lot of vibration that is experienced. With a screw we all knows what happens when it’s around vibration, they tend to loosen up. With the cage clamp, vibration typically doesn’t matter. It moves and it adjusts and responds to the vibration without coming loose over time.
Now think about what it costs if you’re having to install hundreds of terminals in a given control panel. If you’re having to screw and tighten down each and every terminal, that’s going to take quite a bit of time. But with the cage clamp, all you basically do is insert a screwdriver, insert your wire, remove the screwdriver and it’s done. You get the same great connection every time. The other thing to consider is first thing in the morning when your fresh, you’re probably going to be tightening down those screws a lot tighter than the last one at the end of the day when you’re kind of tired. So you get a variation of how tight those wires are. And so then what ends up happening is once that panel gets installed in a machine, you’re going to start having loose connections and that’s going to potentially cause a machine to go down and cost you extra money.
So you always want to make sure that you use the right product for the right application. In the case where you have temperature cycling and vibration and you’re looking for the most efficient and best cost to connect your wires cage clamps are definitely the leg up.
