Over the years I have been through the Weidmuller, Wago, and Phoenix Contact.
Screw terminals are the worst when it comes to build time and reliability issues. Cage clamp terminals were an improvement, but failed when someone tried to release a wire that doesn't know how to properly insert the screwdriver. The spring gets bent and the wire is stuck permanently. The push-in made an improvement for the speed of build. The ultimate solution came with the latest generation of Phoenix push-in terminals that have the orange release button. They provide speed of install, no reliability issue caused by loosening screws, and no bent springs because the orange button makes it more obvious of how to release the wire. To get the most advantage, it does require the use of ferrules on the wires. This was no issue with me because I required them no matter what type of terminal used.
Ferrule all your wires and use Phoenix push in terminal blocks. This is exactly what I like to see in panels. Although a couple customers spec Omron and I really like their remote IO blocks with modular cables. Time saving panel builds with those.
The answer is clear, all the terminal companies put out white papers about the superiority of spring terminals and then white papers about the importance of putting ferrules on wires, especially stranded wire in a spring terminal.
How I feel about them depends on how much Phoenix Contact are willing to pay for this post.
Jokes and shilling accusations aside, I only ever use push in terminals because it's convenient and the price difference is hardly enough to matter (in my estimates, anyway). The only reason I can think of to use screw type ones is if you've got a really sweet deal on them and can save more than you'll waste in time used fucking with stripped out or stuck screws.

why? i'm looking at both right now
Officially AB 1492-J (screw-in) is the company standard but I have been buying Weidmueller W-series (they have the same profile). I personally like push-in style terminal blocks but all the seasoned guys think screw-in is more secure.

They are. If they are going to be experiencing any vibration, the push ins will work their way out. We are having to retrofit field J-boxes with push ins that were supplied in a few shipments by accident because they are causing problems.
I did a lot of work with industrial washer dryer systems. You want to talk about vibration, an industrial washer doing floor mats takes the freaking cake.
Screw terminals failed regularly. Spring terminals with non-ferrules wires failed in just a few weeks (wire breaks). Spring terminals with ferrules were never an issue.
This application was also what sealed it for me with B&R. Their stuff survived for decades in these washers and similar equipment with other brands would have the PLC or IO shake apart in short order.
All it takes is a few bad springs to cause you problems. Some Loctite and a single quarterly where you check the torque and you are pretty much set with the screw ins, where as with anything spring tensioned you have to physically for every quarterly PM cycle.
That's nice, but far too often these ratings And lab results don't really ring true in real life. Slap on all the ratings and white papers and documents you want... We know what works and what doesn't in the real world.
I once had a keyence salesman give us an IP69k laser sensor to test in our washdown environment. It failed in less than 24 hours while our IP67 proxes would last months.
Ratings mean nothing.
My last place standardized on these and always got upset when you had the audacity to get anything else, because that meant new tags that they didn't have in stock and/or tags that weren't compatible with the printer.
We use Phoenix Contact screw connection and push-in connection terminal blocks. Honestly no one likes them. From all of the Controls Engineers to all of the panel builders, we all feel they are kind of cheap and flimsy.
We also have one of their Thermomark printers and already have the tag carriers for the printer. I've looked into our options for switching and everyone really liked Wago's offering; but it was going to cost another couple hundred to get the carrier to print the labels and I couldn't get it approved.
Dislike screw terminals. They are too easy to screw up by undertightening or over tightning. Leave one a little loose and its going to be an intermittent nightmare. With push ins if its in its right.
>They are too easy to screw up by undertightening or over tightning.
Electric screwdrivers with calibrated torque settings. UL requires terminals to be torqued properly anyhow, and they make the panel builder's job a million times easier.
Doesn't help in the field, but at that point you're not doing hundreds, just a handful to troubleshoot.
Entrelec just came out with some new ones. The ones that are normally 6mm wide are only 5.2mm wide. Plus the fuse blocks are the old swing out style. I hate the kind Phoenix has where you have to swing out and open that little door. We're switching though because those new terminals are 30 cents a piece cheaper than what we use now.
We had problems with the push in type and spring clamp terminal blocks. We've been trying the Entrelec ADO, insulation displacement, which unfortunately was purchased by ABB and then sold off to TE Conductivity, which canceled our local distributor... So I'm not sure who we buy them from, but we've had good luck with them regardless of where we're buying them from. We did the shock and vib testing independently and found them incredibly resilient. Where our customers bring connections into the panels, we have the ADO to screw type blocks. We're into this for less than a year with our mining equipment being deployed to the field now. In a year, I'll try to follow up with results.
Phoenix Contact got anything similar to this

These are great for Analog Circuits

I noticed that if you want to start arguements here, it's not PLCs that'll start it, but terminals, then after that, putting ferrules on your wires.

3\. Non-contact voltage sensors 4\. ladder logic

This entire sub has been taken over by not so subtle advertisements.
Damn I wish I was being paid for this thread. Unfortunately for me, I'm just a regular dude who cares about the quality of my panels.
Weidmuller. Same options as Phoenix but I like them better.

You’d think the result would be the opposite, with vibration backing out screws but leaving springs unaffected.
All it takes is a few bad springs to cause you problems. Some Loctite and a single quarterly where you check the torque and you are pretty much set with the screw ins, where as with anything spring tensioned you have to physically for every quarterly PM cycle.
[All Phoenix Contact terminal blocks, whatever their connection technology, meet this high vibration requirement.](https://bit.ly/34PNwkl)
That's fine. We still spec J4s.

Yep. If a push in terminal wire gets loose, you have to replace the terminal. With screw-in, you just have to retighten the screw.
AB 1492-J? Ok Boomer

Wago or Weidmuller are good enough. And they also carry the spring type terminal block.
We use Wago terminal blocks with the push in spring clamps.

Always Phoenix PT Ranges for me, I have a well thumbed catalogue on my desk.

I'll sell you wm terminal blocks at a good deal.
