Straight Shrouded Plug for Electronics

The Pomona Electronics 5931-0 is a sheathed banana jack rated CAT III 1000V for electronics work. It suits technicians and engineers who need a shrouded connection point on test leads or panel builds. The straight shrouded plug design helps prevent accidental contact during measurements. Buyers who need an unshrouded or lower-voltage jack will require a different connector type.

Gold-Plated Brass Contacts at 25 A

Gold-plated brass contacts carry up to 25 A through a brass body with a black finish. The shrouded housing insulates the contact area during normal bench or field use. No active cooling or moving parts are present, so the connector runs silent and adds no thermal load to the circuit. Power draw is determined entirely by the external circuit being tested.

Brass Body with 5/8 in Length

The brass body measures 5/8 in long and fits standard banana plug mating faces. The shroud extends over the contact to meet the CAT III 1000V safety rating for installation and measurement categories. Black colour coding aids quick identification on crowded panels or lead sets. Installers needing a different length or panel-mount thread pattern should verify compatibility before ordering.

Questions about this item

How do I install the Pomona 5931-0 sheathed banana jack and what step is often missed?

Insert the straight shrouded plug into a compatible panel cut-out, then tighten the mounting hardware fully; the step often missed is verifying the gold-plated brass contact seats squarely before final torque.

What maintenance or replacement will the Pomona 5931-0 need over time?

Inspect the gold-plated brass contacts periodically for oxidation or wear; replace the jack if contact resistance rises or the black brass body shows cracking from repeated 25 A cycles.

What limit appears first on the Pomona 5931-0 during sustained high-current use?

The 25 A maximum current rating is the first limit; continuous operation near this level heats the brass body and gold-plated contacts, risking degradation before the 1000 V CAT III voltage ceiling is reached.
