12Pin Male Brown Automotive MX150 Mat-Sealed Connector 33482-6203 – TS30359-12P-11-2 Durable Signal Housing for Vehicle Audio & Control Systems

When reliability and precision matter in automotive Electrical Systems, the TS30359-12P-11-2 stands out as a high-performance solution. This 12-pin male connector, featuring a distinctive brown housing and Key C configuration, is engineered to meet the exacting demands of modern vehicle electronics. Designed as a direct match for part number 33482-6203 and compatible with mating housing TS30359-12P-21-2, it ensures secure, error-free connections in car audio, marine systems, and off-road vehicles. Built with advanced sealing, robust retention, and automotive-grade materials, this connector is ideal for applications where signal integrity, environmental resistance, and long-term durability are non-negotiable.

Optimized for Automotive Signal Integrity and System Reliability

The brown TS30359-12P-11-2 connector is specifically designed for use in vehicle audio, control modules, and sensor harnesses where consistent electrical performance is critical. Its Key C design prevents incorrect mating, ensuring that only the correct female housing (TS30359-12P-21-2) can be connected. This polarization feature is essential in complex wiring systems to avoid damage from reverse polarity or mismatched circuits. The brown housing provides a clear visual identifier, helping technicians and installers quickly distinguish it from other connectors during assembly, maintenance, or repair—reducing errors and improving workflow efficiency.

Advanced Mat-Sealing for All-Weather Protection

Each terminal cavity is pre-fitted with a mat seal and protective diaphragm that activates upon wire insertion, forming a tight, waterproof barrier around the insulation. This sealing system effectively blocks moisture, dust, salt spray, and other environmental contaminants from entering the connector. In applications such as marine electronics, off-road vehicles, or under-dash installations, this protection is crucial for preventing corrosion, short circuits, and signal loss. The result is a long-lasting, reliable connection that performs consistently in harsh and variable conditions.

Two-Stage Retention for Vibration and Shock Resistance

Engineered for high-vibration environments, this connector features a two-piece housing with a secondary lock wedge. After Terminals are inserted into the primary housing, the wedge is slid into place, applying uniform pressure to secure all contacts. This dual retention mechanism prevents terminal backout caused by engine vibration, rough terrain, or repeated mechanical stress—common issues in automotive, marine, and utility vehicle applications. The design ensures stable Electrical Contact over time, minimizing the risk of intermittent faults and system downtime.

High-Strength Thermoplastic Housing for Long-Term Durability

Constructed from either PBT+GF15% or PA66+GF30%, the housing delivers excellent resistance to heat, impact, and chemical exposure. These glass-reinforced engineering plastics maintain dimensional stability and mechanical strength across a wide temperature range, making them suitable for use in extreme climates—from sub-zero winters to high-temperature engine bays. The brown color not only aids in visual identification but also offers UV resistance, preventing discoloration and material degradation when exposed to sunlight.

Flexible Terminal Options for Custom Wiring and Repair

The TS30359-12P-11-2 supports multiple terminal types, including copper alloy, brass, and phosphor bronze, allowing users to optimize for conductivity, cost, and mechanical durability. Its standardized 12-way layout is compatible with common crimping tools and widely used in automotive aftermarket upgrades, factory replacements, and custom harness builds. Whether used in a car stereo retrofit, marine control panel, or UTV electrical system, this connector provides a reliable and serviceable solution for professional and DIY applications alike.

Wide Range of Applications Across Vehicle Types

This connector is ideal for:

• Aftermarket head unit and audio system installations

• Factory harness repairs and replacements

• Infotainment and navigation system integration

• Control wiring in yachts, boats, and marine vessels

• Electrical systems in UTVs, ATVs, and agricultural equipment

Its sealed, rugged design ensures dependable performance in both indoor cabin environments and exposed outdoor installations.
