content: Does anyone recognise what series this 2-pin connector is?Basically it's a standard 0.1", 2 pin connector but with a polarising lug but I've stared at too many pics on the Farnell and Mouser web site without finding an exact match.

content: It also didn't help looking at the wrong category on Farnell's web site - as it clearly comes as the crimp pins plus housings I looked in the "Plug & Socket Connector Housings" section whereas the 2-way housing is in "PC Board Connectors".Bizarely the 5-way, 6-way and 7-way versionisin "Plug & Socket Connector Housings"Sometimes I think Farnell do it on purposeThey're out of stock on the 2-way anyway so I ordered some from Hong-Kong off of ebay for 1/3 of the price.

But that kind of difference adds up over time, which is one of the biggest reasons why I wish the entire electronics industry would give up on imperial measurement. Makes PCB footprints a pain in the butt constantly having to toggle between inches and mm.And this coming from an imperial native.

content: Does anyone know which manufacturer has these or where to get something compatible at least ?It is from friend's ASUS X54H laptop. The logo on the top seems to be a seahorse.Thanks in advance.

content: QuoteSort-ofIn the UK we use a fairly restricted range of sizes - I suspect most domestic stuff was covered by 1/2", 3/4" and 1". These were internal measurements so when we moved to metric sizes the closest were 15, 22 and 28mm - these being outside diameters. You can throw in 8mm and 10mm (outside diameter) "microbore" pipe sizes for modern installations.For threaded joints we use "British Standard Pipe" threads, commonly found on compression joints etc.The French use a wider range of pipe sizes - basically anything from 8mm OD up in 2mm increments to 22mm then 28, 32 and 40mm. Their pipe tends to be 1mm wall thickness as well compared to 0.7mm typical in the UK. They quite like to hard solder (braze) their joints although there is regional variation and soft solder (lead free) is acceptable - especially for DIY.For threaded connections they do, indeed, use BSP threads but they seem to use a much wider range of fittings than is typical in domestic UK installations.So the actual pipework is all metric but the threads on some connections are imperial.

content: My favorite metric size is the standard tripod-mounting screw: M6.35 . Otherwise known as 1/4-20 UNC.
