Wanted: smaller alternative to DB9 connector, but still robust

what about RJ 45's, they are 8pin, and the cable, sockets and ends are cheap, yet small.

otherwise you can use the mini-din connectors like svideo connectors with more pins

minifit juniors they are the way to go or you could try a small euro connector its wire wrapped but it will withstand an earthquake!

Also molex microfit connectors

I'd considered RJ45 connectors, but the cable that's already attached to one of the devices I need to connect isn't really suitable.

Also, although they may well exist, I don't think I've ever seen an RJ45 cable mounted socket.

In my experience, mini-din connectors fail my robustness requirement.

Thanks, Peter

There are small pvc enclosures with RJ45 sockets built in, some have crimp pins, flying leads etc. Options for the "back" of the socket are D9 or cable. Look at C&K Switches Plus or whatever there name is this week.

Without knowing all your needs this info may or may not be useful.......

How about the Hirose miniature round connectors - metal with screw or push on locking. Expensive though. Farnell have them and I guess also RS. There is a similar Fujitsu range but don't know where you would get them

How have you found the cable retention on those Hirose units? IMOE it sucks.

you can get an rj 45 connector which is like a punch down style connector. it has rj45 shielded (rj48c)on one end and a small 8 wire punch down block on the other end and it is all consealed in a nice neat backshell. i have a few of these if you want to try

Thanks for the offer, but it sounds like it'd be bigger (or at least much the same size) as the DB9 that I wanted to be smaller than.

You may want to look at the "b" series of Lemo connectors. Much smaller than D connectors, much much more rugged, much much more expensive!! Maybe there is another source in Australia - I get mine from John Barrys. regards GrantR

Try a micro DIN plug similar to those used for keyboards on some computers. They are available with up to 8 pins and are readily available from many electronic component suppliers

I agree, it sucks! I had some cables made up in China using the Fujitsu Connectors (very similar to the Hirose) and they crimped the strain relief and also used some kind of superglue. Worked quite well.

Biggest problem is soldering those darn small pins!
