Benefits of a Red Automotive Audio Connector

The red housing of the TS30243-28P-11-5 serves as a clear visual indicator, helping technicians quickly identify the correct connector during stereo installation or maintenance. This is especially useful in vehicles with multiple harnesses or in service centers handling high volumes of installations. The color red is often associated with primary or critical circuits, making it an intuitive choice for main audio signal connections. It also supports color-coded wiring strategies, improving organization and reducing human error in complex upgrade projects.

Durable Construction for Long-Term Reliability

Manufactured from high-strength thermoplastics such as PBT+GF15% or PA66+GF30%, the connector housing provides excellent resistance to heat, impact, and environmental degradation. These materials maintain structural integrity across extreme temperatures (-40°C to +120°C), ensuring long-term performance in demanding automotive environments. The internal Terminals are made from copper alloy, brass, or phosphor bronze, offering superior electrical conductivity, low contact resistance, and strong resistance to oxidation—critical for maintaining high-fidelity audio signals and stable power delivery.
