I need help identifying a vintage connector.. does anyone have an idea what this 12-pin plug is called, or can provide me with a link to the appropriate counterpart (or even have one at hand to sell me)? This is on a Siemens paper tape reader, ca. 1960, originally meant to be connected to a Gretag Tape Sender. Boosts appreciated :-)

@WooShell@chaosfurs.social did you try this? https://connectorbook.com/identification.html?Q=

@WooShell@chaosfurs.social It looks like the military MIL-DTL-5015 standard (https://en.wikipedia.org/wiki/MIL-DTL-5015) in terms of pin arrangement, but then it looks like it has a bayonet mount instead of a screw mount?? Maybe some IBM mainframe sorta thing derived from the military standard

@WooShell@chaosfurs.social this is what Claude tells me: The alphabetic pin-lettering (skipping easily-confused letters like I and O) combined with the bayonet coupling and blue dielectric insert is a strong signature of a MIL-spec style circular connector — this family (often seen as MIL-DTL-26482 / "MS" series, or equivalent commercial versions from Amphenol, Souriau, ITT Cannon, Fischer, or Tuchel) is very common on vintage test gear, avionics, and lab/medical instruments from roughly the 1960s–90s.

@WooShell@chaosfurs.social https://m.pcbterminal-block.com/sale-42936258-siemens-ip67-waterproof-male-female-12-pin-m23-circular-connector-etype-ptype.html The search term I used was: Siemens/Tuchel circular connector 1960 12 pin. I think you would have more luck trying to identify the exact model of tape reader and finding some sort of manual.

@WooShell@chaosfurs.social Early (1960s to 1990s) high precision measurement amplifiers for strain gauges by hbm.com used a similar type of this connectors. But they were screwed in while yours got a bayonet. I know that HBM bought these connectors somewhere to sell them together with their sensors, but I don't know the manufacturer. HBM calls them "Greenline". Not sure if that helps.
