Technical Specifications

Why Choose a Black Key B Male Connector?

The black housing of the TS30243-28P-11-3 is designed to match the OEM aesthetic of factory Toyota wiring systems, making it ideal for installations where visual consistency is important. Unlike brightly colored connectors, black blends in naturally with the vehicle’s existing harness, creating a clean, factory-original look after installation. This is especially valuable for dealerships, resale preparation, and high-end audio shops where a discreet, professional finish is required. The "Key B" designation ensures compatibility with a specific generation of Toyota audio interfaces, preventing mismatches and ensuring plug-and-play functionality.

Durable Construction for Automotive Applications

Built from high-performance thermoplastics—PBT+GF15% or PA66+GF30%—this connector offers excellent resistance to heat, impact, and chemical exposure. These materials maintain structural integrity across a wide temperature range (-40°C to +120°C), preventing cracking or deformation over time. The Terminals are crafted from copper alloy, brass, or phosphor bronze, providing superior electrical conductivity, corrosion resistance, and mechanical resilience. This ensures stable signal transmission and long-term reliability in demanding environments such as daily commuter vehicles, off-road UTVs, marine yachts, and industrial equipment.
