Hi Sean - That does look like an Omnetics connector (which I have never seen or used!= ) If you were in Australia I would suggest: In stock too. Pricey though! (note - the picture is for a 5 pin but the des= cription is for 12 - mating connector: < http://www.cseonline.com.au/A22007= -001-MCS-12-WD-18.0-C-12-Socket-w-18-leads-A22003-0011.html> ) If this is one off, and there is sufficient lead length, I would cut the or= iginal connector off with enough tail to fit a different (common) connector= between the device and the original. That way you can access the signals b= ut still restore the original connector (12 pins though - ugh!).

Subject: [EE] Connector source Hi all, I'm trying to find the mating connector for this: https://ibb.co/dObgLa The connector is part of the electric motor-driven focus mechanism on a tel= ephoto IR thermal imaging lens assembly from a high-end security camera. It was an awesome eBay find (a fraction of the usual price of such things) = but now I have to actually figure out how to interface to it and part of th= at mystery is to find a mating connector. The OD of the white plastic shell is 0.267 inch (6.78mm). The 12 contacts a= re gold-plated (the flash on the camera makes them look otherwise). They ar= e little tubes rather than solid pins. They seem to be about 0.03 inch diam= eter each (0.76mm) and their inner diameter seems to be 0.022 inch by a go/= no-go pin gage test (0.558mm). Note the flat side of the inner space which = acts as some kind of keying feature. As best as I can tell, this is a "Micro Plastic Circular" connector by Omne= tics. The mate is probably part number MCP-12xx where xx indicates the type= of termination you want, which I am not picky about since this is a one-of= f. There is no marking on the connector itself but an extensive Google imag= e review for "circular connectors" allowed me to find similar ones which I = then traced to Omnetics. What I'd really like to know is whether there are any crosses for this part= which are more available than Omnetics OR is there a source which sells Om= netics' connectors? They don't seem to use the typical distribution channel= s. Any help appreciated!
