12Pin Male Green Automotive MX150 Mat-Sealed Connector Key D 33482-6204 – TS30359-12P-11-3 High-Integrity Signal Housing for Cars, Marine & Off-Road Vehicles

In the evolving landscape of vehicle electronics, where audio, navigation, and control systems demand flawless connectivity, the TS30359-12P-11-3 emerges as a trusted solution. This 12-pin male connector, featuring a vibrant green housing and Key D configuration, is engineered for precision mating and reliable signal transmission in automotive, marine, and utility applications. Designed to match the specifications of part number 33482-6204 and compatible with mating housing TS30359-12P-21-3, it serves as a critical link in wire harness assemblies where durability, correct polarity, and environmental protection are paramount. Whether used in a high-end car audio upgrade, a yacht’s control panel, or an off-road UTV’s electrical system, this connector delivers consistent performance under real-world conditions.

Engineered for Precision and Reliability in Automotive Signal Systems

The TS30359-12P-11-3 is more than just a connector—it's a precision-engineered interface designed to ensure error-free signal transfer in complex vehicle environments. The Key D configuration prevents accidental mating with incompatible connectors, eliminating the risk of reverse polarity or damaged electronics during installation. This feature is especially valuable in modern vehicles where multiple connectors may look similar but serve different functions. The green housing provides visual differentiation, helping technicians and installers quickly identify the correct component during assembly or repair.

Mat-Sealed Design for Superior Environmental Protection

Each terminal cavity is equipped with a pre-installed mat seal and protective diaphragm that forms a watertight barrier around the wire insulation when inserted. This advanced sealing system effectively blocks moisture, dust, salt, and other contaminants from entering the connector body. In demanding applications such as marine electronics, off-road vehicles, or under-hood installations, this protection is essential for preventing corrosion, short circuits, and signal degradation. The result is a long-lasting, maintenance-free connection that performs reliably in harsh conditions.

Robust Two-Piece Housing with Secondary Lock Mechanism

To combat the effects of vibration and mechanical stress, this connector features a two-piece housing design 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 system ensures that terminals remain firmly in place, even in high-vibration environments like engines, rough terrain, or marine propulsion systems. It’s a critical safeguard against intermittent connections and terminal backout, which can lead to system failures and costly repairs.

Durable Thermoplastic Construction for Long-Term Stability

Made from either PBT+GF15% or PA66+GF30%, the housing offers excellent resistance to heat, impact, and chemical exposure. These glass-reinforced materials maintain their structural integrity across a wide temperature range, ensuring reliable performance in both freezing winters and scorching summer conditions. The green color not only aids in visual identification but also provides UV resistance, preventing fading and material breakdown over time—ideal for applications exposed to sunlight or outdoor environments.

Versatile Terminal Compatibility for Custom Wiring Projects

The TS30359-12P-11-3 supports a range of terminal types, including copper alloy, brass, and phosphor bronze, allowing users to select the best option based on conductivity, cost, and mechanical strength requirements. Its standardized 12-way layout is compatible with common crimping tools and widely used in automotive audio, control modules, and sensor harnesses. Whether used for factory replacements, aftermarket upgrades, or custom-built systems, this connector offers flexibility without compromising on performance or safety.

Ideal for Automotive, Marine, and Off-Road Applications

This connector is widely used in:

• Car stereo and infotainment system installations

• Factory and aftermarket audio harness replacements

• Marine electronics and navigation systems in yachts and boats

• Electrical control units in UTVs, ATVs, and agricultural machinery

• OEM and repair applications requiring sealed, reliable connections

Its rugged design and environmental sealing make it suitable for both indoor and outdoor vehicle systems.
