RJ11 connector problems

I am working on a coin-op redemption game that uses regular telephone wire and connectors to connect all of the sensors and lights and so forth. They use this RJ11 connector that is not as wide as most of the ones I have seen and I am having a hard time finding the correct crimper for this size. Does anyone know what these connectors are called? It is a 4 pin connector and looks just like the ones you have on your phone but it is less wide and jiggles when you put it in a the more common wide type. This has been very frustrating. I tried every crimper at Home Depot and Radio Shack. They say they are for RJ11 but are to large for these. I think these might have been common before they went to 6 wire RJ11. They had to make the 4 pin plug wider to fit into the same female adaptor as the 6 pin so they just added some plastic onto each side. When you crimp with the newer ones the extra bars that push the two extra pins on each end for the 6 pin are just empty on the wide 4 pin. But on the narrow 4 pin you end up fracturing the plastic because of those extra pins one each end. They push into the body and never align correctly anyway. I hope this is making sense. I need to know what crimper to buy that will work with these. They did have a cheap plastic one that seemed to fit but didn't align correctly. The manufacture of the game isn't much help. Thanks

Well, RJ11 is 6P4C, that is 6 positions, 4 connectors. RJ45 is 8P8C, 8 positions, 8 contacts. Yours looks like 4P4C which like martin said, I think is called RJ12.

You can get cheap RJ11/RJ12/RJ45 crimpers on eBay.

Probably this one (RJ22). Whip out your calipers and check it.

Called a "handset" connector. You can get a decent crimping tool with an appropriate die set for around $80-$150 USD, and probably many cheaper ones which are not as good.

Eg.

It's been some years I had a discussion on this topic in SEB. It turned out that these RJxx defines pin identities and functions in a telco environment as defined by ANSI.

The plugs you're looking for are 4p4c mini modulair plugs. Don't know were you live, but I can buy 4p4c, 6p4c and 8p8c (often misnamed RJ45) along with the crimpers in any DIY market.

That's the kind they use on handset cords. I don't know the RJ number, but there _has_ to be something out there - there are two per telephone, after all, just like the wide ones. :-)

Or, you could just buy a pile of handset cords, and use them. :-)

Good Luck! Rich

That's probably an RJ-22 which is the same as is used on 'phone handsets. Crimpers and plugs available from Mouser, if memory serves corrcetly....

No, it's not RJ22, it's 4p4c modular connector.

But yes, Mouser 154-7616 for the connectors and 382-8100 for the crimp tool.
