J74MST-R SCHEMATIC

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.

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 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.

Normal-Thru Patch Jack

Self-terminating

J74T-R

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.

Dual Patch Jack

Normally-terminated

J74-2T-R

Provides a resistive load.

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.

R-Resistance (½W, 1%). For standard panels see page 51.
