10 Pin Circular Connectors for Power Supply Link

Interconnect Circular Connectors

Hi DigiKey Team,

I’m building the interconnect cable between two power supplies (“PSU-2AMR-A” and “PSU-2AMR-L”) for a DDA AMR-24 console. I need help identifying the exact shell size and part numbers for the MIL-DTL-26482 Series I connectors so I can order both cable ends, backshells, and suitable cable.

What I have:

Circular connectors, metal, bayonet coupling, single keyway.

  • Jam-nut (single-hole) panel receptacles on the PSU faces (female contacts).

  • 10-contact insert arranged 8 around + 2 in the center (side-by-side).

  • The barrel OD is about 0.50″ (≈12.7 mm), so this is the smaller Series I form factor (likely shell 12 or 14S, not the larger 97-series).

  • This seems to correspond to MIL-DTL-26482 Series I (Amphenol PT / 62GB / MS311x family).

What I need to buy (please provide exact in-stock part numbers/SKUs):

  1. Straight cable plug, pins — MS3116, shell size to match my receptacle, 10-contact “8+2” insert (e.g., MS3116F*[shell]**-10P*).

  2. Straight cable plug, sockets — same shell/insert, 10-contact, (e.g., MS3116F*[shell]**-10S*).

    • I’m making a plug-to-plug cable (one end with pins, the other with sockets) to link the two PSUs.

  3. Backshells / clamps for both plugs, sized for ~0.35–0.45″ cable OD (please recommend).

  4. (Optional, if you stock them) Jam-nut panel receptacle with sockets — MS3114, same shell/insert (in case I ever need to replace a PSU chassis connector).

  5. Cable recommendation: 10-core, 16–18 AWG, shielded multi-core suitable for low-voltage DC rails (±18 V and ±26 V; up to a few amps per conductor), jacket OD that fits the backshell you recommend.

Attachments: face photos of the PSU connectors and a simple “8-around + 2 center” insert sketch.

Please confirm the shell size from my photos (likely 12-10 or 14S-10 insert arrangement) and send me orderable part numbers (and any needed suffixes for plating/finish).

Thanks so much,

I just realized, that the letters HRS are on the plastic Insert of the female connect. That means I am looking for a HiRose connecter. Thanks in advance.

Hello mmcqueen and welcome to the DigiKey TechForum.

The connectors do appear fairly similar to the RM series from Hirose, these options are the 15 shell size, 10 position plugs. There are options for female and male contacts. These are assemblies that include contacts, backshell, cable clamp, and either coupling nut or strain relief.
For cable options, I found the 18AWG, 10 conductor options linked HERE that may work for your application.

Measuring the threads I am really close to .075 Inches. I think I am going to be RM12 instead of 15.

On second thought, I dont know. I can’t seem to find and RM12 that looks correct.

I took the connectors off and clipped the wires. There are only 4 wires on each connector. I could now use any 4 pin circular connector that will fit.

What is the panel hole size?

The whole is 5/8”

How about a M12-4 connector 1754-M12A-04PMMS-SF8001-ND.

Here is the spec sheet. Panel hole size is 15.4mm.
