Hilitchi 40-Pieces 2 3 4 5 Pin 16mm Thread Male Female Panel Metal Aviation Wire Wire Connector Plug Assortment Kit (2 Pin / 3 Pin / 4 Pin / 5Pin)

The reviewer that gave these 1 star really annoyed me. I am a professional panel and systems designer. I work with various quality grades of parts every day and to compare these to professional Indy-Car connectors is quite frankly ridiculous. Lets be blunt here. Would I use these where human life or tens of thousands of dollars was at stake if it failed or where they were going to be pulled on and off regularly or where they are going to be subjected to serious extreme environmental conditions like under the hood of an Indy car - no I would not. However the high quality connector the reviewer who gave these 1 star mentioned cost my company $13 each for the panel mount and $8.75 each for the plugs when you buy them in quantities of 50 or more. That means on average a pair costs over $22. What the heck did he expect when a box of 16 pairs is being sold for $20? I needed an assortment of different pin counts to make a PLC test box that I can use with 5 different PLC vendor setups. To have a virtually identical test box for each setup would be very expensive but by making my own and using these connectors I can test over 25 different sensors on 5 different types of PLC with 1 test box. I purchased a mixed box of the 2 to 5 pin and a mixed box of the 6 to 10 pin, total cost $40. Had I used high grade connectors which I can get from work at cost just those connectors would have cost me in excess of $350. These connectors on my test box are unlikely to be plugged or unplugged more than once a week and the sensor items may not even be screwed together during the test so I couldn't care less if it was difficult and personally I find them very easy to mate up together and the quality is pretty good for the use I need them to do. Overall I think these are great value for money and work well for me for simple test box applications. See the pictures. For those of you who don't want them to spin during assembly then instead of using a round 16mm hole you can use a "double D" with a 15.4mm major diameter and 14.6mm across the flats. If you don't understand that last comment just cut 16mm round holes for them!

Overall good, but the hollow post is too shallow and makes it difficult to solder

Love these connectors they are not military grade but they are great for normal usage just ordered my second set of them. Only issue MAKE SURE ALL THE STRAIN RELIEF SCREWS are included they are small and not a size you are likely to have spares. Of the 20 pairs maybe 10 had a screw come out in shipping I assumed. This was a bad assumption only 7 came lose in shipping 3 must have come lose when the units were packaged net result I had 3 incomplete units combining units still left me with 2 incomplete units. Not much of a problem because you are not likely to need every unit of every size (A have unused 3 pin's) but still make sure you check so you don't get caught short. Took me a couple of months to get to the end of my supply and therefor it was to late to get a replacement or refund but still love the product and am reordering past experience with shortage or missing parts has been great so Had I noticed in time I assume there would not have been a issue.

These were a great value compared to others on the site. I'm using some to connect an oven to a microcontroller. The only thing to note with these, the pins are quite small and crowded together. 35 years ago, I could have soldered these without an issue.. now: not so much. but I would buy them again if I use up what I have

I have a Yaesu FTDX-3000 radio and was looking for something to make my boom mic work with my transceiver and the 8 pin connector that comes with this is exactly what I needed. I cut my xlr cable (make sure it is a quality cable that has 3 wires not 2) and wired it to the right pins on the radio and it worked great. I also used a push button wired to this same connector to activate my push to talk. I purchased this so I could have other connectors in case I have a project in the future as this whole kit was cheaper than 1 adapter cable which I made using just one piece of this kit.

These are reasonably well enough made for use in hobby projects. They don't seem to be on par with professional parts, being a little loose in tolerances. However, they work fine for projects.

These connectors are great, I love them. My only complaint would be that the female connectors have large posts that are nickel or chrome coated and difficult to solder to with lead free solder. Not impossible mind you, you just have to build heat on the post before adding your wire and solder. When I use 66/34 solder, it's not an issue. Still a great value and very useful connectors.

I needed a few multi-pin connectors for a project I was working on, and I thought I would try out this assortment, not expecting them to be very high quality. I'm extremely happy with them. They solder well, both male and female, and mate strongly. The metal is not nickle plated like what I have been using, but I'm not paying $8.00 each for them either. These are perfect for almost all of your multi-pin connections for your projects.
