12Pin Male Grey Automotive MX150 Mat-Sealed Connector Key B 33482-6202 – TS30359-12P-11-1 High-Density Signal Housing for Cars, Yachts & UTVs

In the intricate world of automotive electrical architecture, precision connectors are the silent enablers of seamless performance. The TS30359-12P-11-1 stands as a prime example: a 12-pin male MX150 series connector engineered to deliver robust, reliable signal transmission in demanding environments. Designed to meet the specifications of part number 33482-6202 and compatible with mating housing TS30359-12P-21-1, this grey-colored housing is a critical component in modern vehicle systems—from factory-installed audio units to aftermarket control harnesses in cars, yachts, UTVs, and specialized machinery. Built with durability and environmental resistance at its core, it ensures uninterrupted connectivity where reliability is non-negotiable.

Precision-Engineered Male Housing for Secure Automotive Signal Transfer

The TS30359-12P-11-1 is not just another connector—it’s a mission-critical interface designed for applications where signal integrity and mechanical stability are paramount. As a male housing in the MX150 series, it features a distinctive grey body and Key B configuration, ensuring correct polarity and preventing mis-mating during installation. This design is particularly valuable in complex wiring systems such as vehicle audio, sensor networks, and electronic control modules, where incorrect connections can lead to costly damage or system failure.

Advanced Sealing Technology for Harsh Environments

Equipped with an integrated mat seal system, each terminal cavity includes a protective diaphragm that forms a watertight seal around the wire insulation upon insertion. This prevents moisture ingress, dust accumulation, and corrosion—common causes of electrical degradation in automotive and marine settings. Whether exposed to engine heat, road splash, or saltwater spray, the TS30359-12P-11-1 maintains optimal performance and longevity, making it ideal for use in cars, yachts, UTVs, and off-road vehicles operating in extreme conditions.

Robust Two-Piece Construction with Secondary Lock

Safety and reliability go beyond basic latching mechanisms. This connector employs a two-piece housing design with a secondary locking wedge that secures all Terminals after insertion. This dual retention system effectively prevents terminal backout caused by vibration, thermal cycling, or mechanical stress—ensuring consistent Electrical Contact over time. The result is a stable, long-lasting connection that meets the rigorous demands of both OEM and aftermarket applications.

Durable Materials for Long-Term Performance

Manufactured from high-grade thermoplastics—either PBT+GF15% or PA66+GF30%—the housing delivers excellent resistance to heat, impact, and chemical exposure. These glass-reinforced materials maintain structural integrity across a wide temperature range, from freezing winters to scorching under-hood environments. The grey color provides UV resistance and visual differentiation, helping technicians identify circuits quickly during installation or maintenance.

Versatile Terminal Compatibility and Wiring Flexibility

The TS30359-12P-11-1 supports a variety of terminal types, including copper alloy, brass, and phosphor bronze, allowing users to balance conductivity, cost, and mechanical strength based on application needs. Its standardized 12-way layout and compatibility with common crimping tools make it easy to integrate into custom harness builds or factory replacement projects. Whether upgrading an audio system or repairing a control module, this connector offers flexibility without compromising reliability.

Ideal Applications Across Automotive and Industrial Sectors

This connector excels in a wide range of uses:

• Factory and aftermarket audio and infotainment system upgrades

• Engine control unit (ECU) and sensor wiring harnesses

• Marine electronics and navigation systems in yachts and boats

• Electrical interfaces in UTVs, ATVs, and agricultural equipment

• OEM replacements and custom control panel assemblies

Its modular design supports both small-batch repairs and large-scale production.
