Pomona 3846 BNC adapter with brass body and PTFE insulation

Pomona Electronics

Pomona Electronics 3846 BNC Adapter Female to Female 500 Vrms measurement tool

SKU CH-6CV0-2ZP4J

Connects two male BNC cables with 50 Ω impedance and 500 Vrms rating across -65 to 165 °C

  • TypeElectronic
  • Connects two male BNC cables securely
  • Rated for 500 Vrms continuous voltage
  • 50 ohm impedance preserves signal integrity
  • PTFE insulation withstands -65 to 165 °C
  • Brass body with beryllium copper contacts resists corrosion

BNC Female-to-Female Adapter 3846

The Pomona Electronics 3846 connects two male BNC cables or test leads in a straight line. It is built for engineers and technicians who need a reliable 50 ohm path in RF and instrumentation setups.

Replaces worn or mismatched couplers

Swap this in when an existing adapter shows intermittent contact or when the impedance must stay at 50 ohm. The 500 Vrms rating covers typical bench signals, and the PTFE insulation maintains performance from -65 to 165 degrees C.

Simple push-on installation

No tools are required; seat both male connectors fully to avoid reflection from an air gap. The brass body and beryllium copper contacts resist corrosion, but debris in the threads can degrade the 50 ohm match.

Questions about this item

What BNC connector size does the 3846 adapter accept on each end?

Each end accepts a standard BNC female connector, allowing two male BNC plugs to join through the 50 ohm impedance path.

How do I install the adapter without damaging the PTFE insulation?

Hand-tighten each BNC male plug until the bayonet pins lock; avoid pliers so the brass body and PTFE insulator are not over-stressed.

When should I replace the adapter if it sees temperatures near 165 degrees C?

Inspect the beryllium copper contacts for loss of spring tension or discoloration after prolonged exposure at the upper temperature limit; replace if contact resistance rises.
