White Female Connector for Factory-Style Audio Integration

The TS30243-28P-21-2 features a white housing that closely matches the color of original equipment manufacturer (OEM) wiring harnesses, ensuring a clean and professional appearance under the dashboard. This color choice helps maintain a factory-like finish, making it ideal for installations where visual consistency is important. The connector is designed with precise alignment guides and secure locking mechanisms to ensure a tight, vibration-resistant fit when mated with its corresponding male plug. This prevents accidental disconnections and ensures long-term reliability in automotive environments.

Engineered for Automotive Durability

Constructed from high-performance thermoplastics—PBT+GF15% or PA66+GF30%—this connector offers excellent resistance to heat, impact, and chemical exposure. These materials provide dimensional stability across a wide temperature range, preventing warping or cracking over time. The internal Terminals are made from copper alloy, brass, or phosphor bronze, delivering high electrical conductivity, low contact resistance, and resistance to corrosion. This ensures consistent signal integrity for audio, power, and control functions in various applications including passenger vehicles, marine yachts, UTVs, and industrial equipment.
