Parts and Pins for Molex connectors

For the V-infinity supply, the part numbers are:

3-position shell with ramp: 09-50-3031
4-position shell with ramp: 09-50-3041
sockets: 08-50-0106
all can be bought from Mouser

How the part numbers for the Lambda supply were found:

1. The shell that was in the supply from a previous user had the following number on it: MXJ 5199
2. Google searches got hits on both MXJ and 5199. The google hits for the 5199 were for datasheets for compatible sockets on Molex's website. Oddly, the pins seem to also be compatible for the "SPOX" connector line which seems to have no resemblance to the header and socket type connector that I was trying to find information about. Handy link to the page that had the link to the 5199 sockets. The header shown looks just like the one on the supply: http://www.molex.com/datasheets/pdf/0010311038_PCB_HEADERS.pdf
3. There is a molex 5199 series document which seems to list specs for the pins: http://www.molex.com/pdm_docs/ps/PS-5199-001.pdf
4. Eventually I traced from the pins to the shell drawing pdf, which even showed the raised 5199 markings. This gave me the Molex part number which is 10-63-3044:
http://www.molex.com/pdm_docs/sd/010633044_sd.pdf
Note that the three part number is called an "EDP. NO." number while the 5199 is called an "ENG. NO.". The EDP number is the one that appears in distributors' lists.
5. Note that this connector is neat because pin 1 is offset from the others by a half a pitch of dead space in the shell.
6. There was confusion of the meaning of number of "circuits". It seems to mean the number of pins aside from pin 1?
7. The shell's EDP number was found at MOUSER but is not available.
8. The molex page for 5199 shows the sockets under "use with", options are 5225 and 5194. The links for these bump me to lists of series with 10-digit numbers with no dashes but which seem to be EDP numbers.
9. Plugging all the socket EDP numbers, with dashes put in at the 4-2-4 intervals similar to other MOLEX part numbers at MOUSER got hits for all, but only a few were in stock:
08-70-1031 is a part number for a bag of 5000
08-70-1030 is individual sockets of the same type
10. Note that the socket drawing from molex is at:

Berg Headers

Berg is a genericised name for crimp-to-wire headers. The ones we bought are from Newark, made by FCI. FCI's web site (http://portal.fciconnect.com/portal/page/portal/FcicntPublic/HomePage) is great.

The connector bodies are these:

specifically the PV
http://portal.fciconnect.com/portal/page/portal/FcicntPublic/PVCrimpToWireHousings

For some reason the contacts we buy, 48236-000LF don't appear as PV contacts, but are compatible and a valid part number. The PV contact part number under the PV menu seems to be 47565-002LF. Also the PV contacts come in varying grip strengths to prevent impossibility of insertion and removal for high numbers of contacts. See:

HD-104 backshells

Aside from Glenair, few sources exist for backshells for HD-104 connectors, which are the rarely used "size 6" D-sub body, slightly bigger in all dimensions than the DD-50 or "size 5".

Strangely, the faeries put a size 6 backshell in one of my desk drawers, I don't know where it came from, and still haven't figured out how to buy them in the U.S.

They are made by a company called Inotec out of Germany. Their website in english: http://www.inotec-electronics.com/cms/servlet/Query?node=108422&language=2

Their german website translated by google: http://translate.google.com/translate?hl=en&sl=de&u=http://www.inotec-electronics.com/

Their catalog: http://www.inotec-electronics.com/cms/files/1/22286618732500.pdf

Search the catalog for part number DG104MSX.

Technique for converting 24-bit jpegs to B&W bitmaps:

1) (possibly optional) save as a 4 bit bitmap
2) Set gamma correction to 0.01 (in IfFanView, possibly in other programs, under color correction)

Note: The pinout images, possibly stolen from Norcomp can be seen at interfacebus.com:

COTS Twinax connectors

While no longer looking for these, here are links to the most promising leads to BNC-sized COTS Twinax connectors:

These connectors from Blackbox, undoubably mfr'd by someone else, are compatible with an old IBM-style serial connector:

http://www.blackbox.com/Store/Detail.aspx/Twinax-Connector-Single/FD010 IBM part# 7362229

http://www.blackbox.com/Store/Detail.aspx/Twinax-Termination-Cap/FD115-R2 Termination cap. Note absolutely no info on what the termination resistance is.

http://www.blackbox.com/Store/Detail.aspx/Twinax-Bulkhead-Connector-Single/FD020 IBM part# 7362229

Amphenol makes a series as well which doesn't look too compatible with the above (but which is available through digikey):

How to pillage Glenair's next day stock

When ordering backshells from Glenair:

The rectangular backshell online catalog here has both D and MDM:

http://www.glenair.com/backshells/rectangular/index.html

each of which shows all of the models with pictures and links to the datasheets. Despite the simple model numbering format given on these top pages, some of these backshells have an actual part number xxx-yyy<+stuff>, while some have xxxTyyy<+stuff> where T is for top exit for wires. Plug the first part of the actual part number, not the simple model number, into the parts search here:

http://www.glenair.com/html/sameday.htm

which is also the 4th link down on the right of the company's home page, and get back exactly which part numbers (i.e. which options) are kept in stock. The home page also has a link to a page showing their distributors, the only recognizable ones of which are TTI (good web site) and Arrow (can only read their site with firefox).

Only a range of in stock part quantities is shown, and if you call glenair sales they still won't tell you exactly how many are in stock, but apparently no matter what there's only a 2-3 day lead time if it's on the list.
