BIRNS Millennium miniature, high-density underwater metal shell connectors are the most advanced of their type:
  • They're strong and tough. Built for rigorous use, BIRNS Millennium connectors feature:

    • Positive stainless steel stops preclude over-tightening.
    • Dual stainless steel keys/keyways for positive indexing.
    • Square "Acme" threads resist mechanical damage.

  • They're designed and built for effective sealing.

    • Every connector uses redundant dual o-rings for effective sealing.
    • BIRNS' exclusive 15o lead-in angle construction ensures o-ring longevity and reliability.
    • BIRNS' inserts are completely sealed, and preclude water ingress through the insert under any circumstances. BIRNS Millennium connectors combine specially designed contacts with special bonding techniques and consistent process control to ensure quality.

    The net result: BIRNS Millennium connectors reliably withstand open-face pressure (Class A). This is a standard feature, available on all BIRNS Millennium connectors.

    [A leading competitor states regarding its own connectors: "Open face pressure resistance is available on most bulkhead connectors (except those with coax contacts) and must be specified when ordering."]
  • They're adaptable.

    • BIRNS Millennium connectors suit "solid" and "oil-filled" cables

    • BIRNS Millennium connectors are ideal for demanding power or challenging signal applications, and/or for electromechanical applications (to 3 tons).
    • Some are available in competitors' mounting configurations to facilitate replacement.
    • BIRNS Millennium connectors permit the use of 22, 20, 16, 14, 12 and 10 AWG contacts in the same connector, without need for cumbersome incompatible "Regular and Long" shell sizes.

    [A leading competitor states: "(Our) connectors are made in two different lengths which we refer to as Regular (or standard) and Long. The long lengths are always necessary when the electrical insert for that given connector contains one or more contacts which are #16 AWG or larger...")]
  • They reliably transmit huge data streams while minimizing electrical noise.

    • Each solder pot is insulated with GRE part way up the solder pot shaft to eliminate electrical interference between circuits.
    • Each contact is plated throughout with a thick, 50μ Ni layer, then a full 50μ of hard gold per MIL-G-45204, Type II, Class 1, to obtain a reliable finish that reduces voltage drop.
      Most connector manufacturers use a thin Ni "flash" under a thin gold layer; although this can lead to gold flaking, they can nonetheless claim that they plated "per MIL-G-45204"... because MIL-G-45204 permits gold plating as thin as 20μ! BIRNS provides 250% more gold, AND qualifies the plating by performing adhesion tests per MIL-G-45204 paragraphs 4.5.2.1 (Bend Test), 4.5.2.2 (Cutting Test), and 4.5.2.3 (Baking Test).
    • Solder pots accept the largest stranding of any wire gauge IAW MIL-STD-39029D.
    • Connector sets have adequate functional contact engagement, per MIL-STD-39029D.

  • They're easy to terminate (i.e. attach wires), reducing installation and maintenance costs.

    • BIRNS Millennium connectors feature replaceable electrical inserts.

      • You can replace the insert when necessary, instead of discarding a connector when the pigtails get too short.
      • You can terminate the wires outside the shell for greater convenience.
      • You have the option of changing circuitry at a later date by simply replacing the existing insert.

    • It's safe and easy to install inserts.

      • Inserts have self guiding keys to make installation easier.
      • BIRNS inserts have exclusive 15-degree molded o-ring lead-in chamfers that won't cut sealing o-rings.

    • BIRNS connectors make it easy to terminate wires, even in high-density applications, due to these exclusive features:

      • Insulation: each solder pot is insulated part of its lengthwith a layer of molded GRE; this facilitates the application of shrink tubing. After wire termination, heat-shrink tubing covers the insulated GRE area, ensuring a completely insulated termination and eliminating possible electrical interference between pins.

      • Easy Soldering Access:
        • No "wings" or other obstuctions limit solder pot accessibility.
        • Each solder pot (even the smallest) has a scalloped end for easier wiring.
        • All scallops face out from center to increase wiring access!
