This document describes the features and characteristics of 3M's D Ribbon Wiremount Plug, including acceptance of wire gauges, low profile, flexible mounting applications, contact design efficiency, physical insulation material, current and temperature ratings, etc.
The D Ribbon Wiremount Plug, Bailmount Option 387 is a low‑profile, flexible connector that accepts 26–28 AWG solid or stranded wire and .050 in round, flat, or jacketed cable. It features a copper‑alloy contact with a 100 µ″ nickel underplate and a 30 µ″ gold wiping area, and includes a stainless‑steel strain‑relief flange.
The connector is rated for 1 A electrical current, insulation resistance greater than 1 × 10⁹ Ω at 500 Vdc, and can withstand 1000 Vrms at sea level. It operates from –55 °C to +105 °C, meets UL 94V‑0 flammability, and is available in multiple mounting configurations with detailed contact and panel dimensions for front or rear installation.
