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 bet-
ter 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 finish, 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.
Monitor-Terminated
Patch Jack

(Use With Front Loading Modular Panels, see page 56)
J74MST-R
Dual Patch Jack
Normally-Terminated
Patent Design
Provides a resistive load.
J74-2T-R
Normal-Thru
Patch Jack
Self-terminating
Patent Design
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.
