Key Product Details

Why Choose a Yellow Female Automotive Connector?

The vibrant yellow housing of the TS30243-28P-21-6 serves as a visual identifier, making it easy to locate and connect during stereo installations. This color-coding is especially useful in vehicles with multiple connectors under the dashboard, helping technicians avoid mismatches and streamline the upgrade process. Unlike black or grey connectors that blend into the background, yellow stands out clearly, reducing labor time and installation errors. This model is often used in harness kits where the female side connects to the vehicle’s factory wiring, ensuring a clean, reversible modification.

Robust Design for Harsh Environments

Manufactured from high-strength thermoplastics—PBT+GF15% or PA66+GF30%—this connector offers excellent resistance to heat, impact, and chemical exposure. These materials maintain dimensional stability across a wide temperature range (-40°C to +120°C), preventing warping or cracking over time. The internal Terminals are made from copper alloy, brass, or phosphor bronze, providing high conductivity, low contact resistance, and long-term corrosion resistance. This ensures reliable signal transmission for audio, power, and control functions in demanding applications such as daily drivers, marine yachts, UTVs, and industrial vehicles.
