What is your favoured cable and connection for durability with a portable analyser?

I am frustrated with local supplier cables failing in around 12 months and a colleague makes some up that don't last more than 6 months using cheap connectors. I want something that will just be tough and durable and last.

Any links to parts are much appreciated.

Thanks Walt there is so many combinations here and many look the same as I'm used to. What combination do you find lasts the longest?

Anyone use a braided for portables?

If you are making your own cables, with BNC connectors, then Kings (brand) is the best I've found, by far.  That said, I don't make my own cable much anymore, though I have everything (and more) that I need to make them.  Just don't have the time.  

As Walt suggests, I get mine from CTC, mostly because they can make anything you need, but also because they have a life-time guarantee.  They seem to be quite a bit more expensive now than they used to be, especially for specialty cables such as a SpeedVue cable for a 2140 (almost $200 USD for an 18" cable).

And be aware they use cheap BNC connectors.  The cable connection is first rate, but the connector itself will wear out and break.  Also, I bought some 4-channel 'boxes' from them for collecting field data on fans with inaccessible bearings.  Nothing fancy, just BNC jacks (w/ female connector).  It wasn't long before I started getting sporadic connections.  Examining them closely, I could literally see that the female barrel had "opened up" and was not making good connection with the make pin on my data cable.  I sent the cards back (the physical boxes were already mounted) and they sent me new ones but said they couldn't find a problem with the old ones, that they worked fine "on the bench".  Wasn't long before the new connectors did the same thing.  So I bought BNC jacks made by Kings on eBay and replaced the connectors.  This was not an easy task, as the old connectors had to be de-soldered, and then the wires soldered back to the new connectors.

Needless to say, I will never buy the boxes from them again.  And this was in spite of communicating personally with CTC's founder and CEO, and explaining they are using "cheap" BNC connectors, and should switch to Kings connectors.  The BNC connector on my data collector cable fails after a couple of years because the little 'tabs' which make up the ground connection are too flimsy and eventually break off.  So it's not just the connector on the field boxes.

Anyways, I still use them because I haven't found a better supplier, who makes it so easy to order exactly the cable you want.

I use CTC cables.  Their life time warranty is unbeatable.  I have used it several times.  Well worth the price which  admittedly is on  the high side. rgds

Use CTC as well As stated above they do have a lifetime warranty so replacing them as they fail is easy. Some of their older junction boxes are terrible but going to be trying out some of their switch boxes so will see how they go.

I'm also a ctc user, lifetime warranty means you only pay for a cable once, but agree with sinski the data collection box's have room for improvement.

I have a 2140 with 5 pin connections on the box. My accels are 2 pin MS which might also be called Mil spec? 

Regards CTC - so if after 12 months my cables been snagged 20 times on various annoyingly placed trunking and door handles etc it finally starts playing up I can just send the whole thing back and they will replace? 
Is this so with coilys too?

Being in the Uk are you using the 'Blue' Cables or the 'Red' Cables? I deal with both companies and haven't really found any issue with either, though the Blue guys are getting a bit expensive of late....think it's something to do with their expansion into North America...without saying anything else too damning ;-).

I thought Wilcoxon were supposedly the bee's Knees or do they only make sensors?

I saw a few CTC setups on an air handling unit in Dublin once and thought they were decent looking enough.
