J74 Series
Trompeter’s superior J74 Series of twinax/triax patch jacks
provide a normal-thru signal path without the use of looping
plugs or patch cords. Same body size as our J24 Series coax dual
patch jacks.
It offers a self-wiping, self-normalizing switch with gold plated
beryllium copper contacts, which provides positive electrical
contact with 30,000 minimum mating cycles.
All metallic parts are machined, formed, or die-casted to
extremely close tolerances which provide better intermateability
improving EMI/RFI suppression and reduced signal loss. The TRB/
TRT patch jack bodies are made of top-quality brass with a bright
nickel-plated, non-tarnish nish, which resists tarnishing and
the associated reduction of conductivity. Dielectrics are made
of machined PTFE for superior dielectric properties and heat
resistance. When you want performance and long-life, these
patch jacks are what you need.

Self-Terminating
Provides a resistive load to the unused side of the jack.
Insertion of a patch plug into the source side automatically
terminates the load side. Plugging into the load side
automatically terminates the source side.
J74-2T-R
Normally-Terminated
Provides a resistive load.

Monitor-Terminated
Plugging into the source side provides a resistive load to
the monitored side. Separate 20 dB isolator jack and
TRB input jacks for monitoring of the normal-thru signal.
