Twinax/Triax Connectors

Twinax/Triax connectors are used when signals require protection form noise through non-signal-carrying shielding.  These interfacing connectors must provide contact surfaces isolated from each other and isolated from the outer shield.  Trompeter twinax/triax connectors have two concentric contacts that are isolated from each other and the shielding connection.

 

Features:

  • All metallic parts are machined/formed to extremely close tollerances.
  • All bodies are made of top quality brass with bright nickel-plated, non-tarnish finish.
  • Fully enclosed, heat-treated, beryllium-copper outer conductor spring (not half hard slotted brass) a patented feature.
  • Heat treated, beryllium-copper center socket contact with 50 millionths inch gold plating.

Series 70/370

 

70 Series ... Miniature 2,3,4 lug and Push-on (TRB)
370 Series ... Miniature Threaded (TRT)

Features:

  • Same size as BNC/TNC connectors.  Large body versions are available to accomodate larger cables.
  • Field serviceable, Wrench Crimp versions for cables with up to .475" outer diameters.
  • Tool Crimp versions for quick termination of cables with up to .250" outer diameters.
  • 3-lug, 4-lug, and threaded versions provide different levels of mechanical stability and keying.
  • Does not require mechanical alignment for mating.
  • QPL'd to MIL-C-49142.
  • Meets MIL-C-49142, 48-hour salt spray requirement.
  • Special plating available to satisfy MIL-STD-1344, 500-hour salt spray requirement.
  • Push-on versions for test cable applications.

 

These concentric twinax/triax connectors are ideal for applications where weight is not a primary concern.  They are commonly used in digital data bus, video pair, MIL-STD-1553B (airborne/ground, primary/redundant), base band circuit and any application for "noise-free guarded" circuits.

 

Series 150/3150

 

150 Series ... Miniature 2, 3, 4-lug, and Push-on (TRS)
3150 Series ... Miniature Threaded (TTM)

Series 150/3150 are concentric twinax/triax connectors for high density and weight reduction applications.  They are commonly used in digital data bus, video pair, MIL-STD-1553B (primary/redundant), baseband circuit and in any application for "noise-free guarded" circuits.  TRS/TTM push-on connectors are designed for blind mate rack and panel applications.  The male plug mates with any TRS/TTM jack and are ideally suited for test cable applications.

 

Features:

  • Same size as TPS/TCM connectors.
  • Solderable Wrench Crimp versions for cables with up to .215" outer diameter.
  • Tool Crimp versions for quick termination of cables with up to .250" outer diameter.
  • 3-lug, 4-lug, and threaded versions provide different levels of mechanical stability and keying.
  • Does not require mechanical alignment for mating.
  • Meets MIL-C-49142, 48-hour salt spray requirement.
  • Special plating available to satisfy MIL-STD-1344 500-hour salt spray requirement.
  • Push-on versions for test cable applications.
