RMS Circular Connectors

RMS MIL-C-26500 (MIL-DTL-26500, QPL-26500)

RMS MIL-DTL-26500 connectors are used for demanding environments. MIL-DTL-26500 come as a variety of connectors within this cylindrical family.

  • Two coupling styles: Bayonet and Threaded Plugs and Receptacles.
  • Both coupling styles inter-mate with MIL-DTL-83723 connectors (exception: shell size 8 threaded, does not mate with M83723 threaded).
  • Aluminum and passivated stainless-steel versions.
  • A variety of mounting configurations.
  • A variety of material finishes are offered such as electroless nickel, olive drab cadmium and black anodizing. Other finishes are available with a commercial equivalent.
  • Alternate key/keyway positions prevent cross mating of adjacent connectors having the same insert arrangement.
  • Positive alignment of pin contacts by the lead-in chamfers of the closed entry hard socket inserts, for select Boeing products.
  • The elastomer grommet is able to seal over a wide range of wire diameters and has a triple wire seal in each cavity.
  • The front release crimped contact retainer system features a retaining clip captivated by molded-in shoulders of each contact cavity in the insulator. This produces a very stable contact.

Can be ordered by military, Boeing, or equivalent RMS part numbers.


RMS MIL-DTL-83723 Series III Connectors (R07)

MIL-DTL-83723 connectors are used in applications with demanding environments. They come in threaded and bayonet versions and are commonly seen in military and commercial aviation. There are varieties of connectors within this cylindrical family, with the following options and characteristics available:

  • Two coupling styles: Bayonet and Threaded Plugs and Receptacles.
  • Both coupling styles inter-mate with MIL-DTL-26500 connectors (exception: shell size 8 threaded, does not mate with M26500 threaded).
  • Aluminum and passivated stainless steel versions.
  • A variety of mounting configurations.
  • A variety of material finishes are offered such as electroless nickel, olive drab cadmium and black anodizing. Other finishes are available with a commercial equivalent.
  • A double-ended plastic tool is used, where one end is for insertion and the other end is for removal of contacts.
  • Alternate key/keyway positions prevent cross mating of adjacent connectors having the same insert arrangement.
  • The elastomer grommet is able to seal over a wide range of wire diameters and has a triple wire seal in each cavity.
  • Positive alignment of pin contacts by the lead-in chamfers of the closed entry hard socket inserts. Raised moisture seal barriers around each pin contact that mate with the lead in chamfers of the hard socket insert.
  • The elastomer grommet is able to seal over a wide range of wire diameters and has a triple wire seal in each cavity.
  • The rear release crimped contact system features a stamped retaining clip captivated by molded-in shoulders of each contact cavity in the insulator. This produces a very stable contact.
  • High-temperature firewall versions.
  • Can be ordered by military or equivalent RMS part numbers.
