Pomona Black Male Test Connector Adapter With Brass contacts and Nickel Plated

This test connector adapter converts BNC‑equipped test instruments to double‑stacking binding post jacks for flexible connection options in measurement set‑ups. It is intended for use in controlled test environments and hand‑held measurement scenarios where conversion between BNC and binding posts is required. The assembly uses non‑conductive moulding to insulate connector bodies and features distinct thumb knobs for attachment of various lead terminations.

• 500Vrms hands‑free rating allows higher controlled voltage tests
• Nickel‑plated brass body resists tarnishing and wear
• Gold‑plated brass centre contact reduces contact resistance
• Insulated captive thumb knob secures wire and plug terminations
• 50Ω impedance maintains signal integrity for test instruments

• Suitable for converting BNC instruments to banana‑plug connections
• Ideal for bench testing in controlled voltage environments up to 500Vrms
• Used with probes requiring low contact‑resistance connections
• Can be used for vertical or horizontal binding post stacking configurations

The dielectric within the BNC is PTFE and ABS moulding insulates the connector bodies.

The Shell and post bodies are nickel‑plated brass while the centre contact is gold‑plated brass.

Wires, spade lugs, pin‑tip plugs and banana plugs can be secured with the insulated knurled thumb knob.

The adapter may be used up to a maximum operating temperature of +50°C.

The insulated thumb knob is captive so it remains attached to the binding post assembly.
