Engineered for Seamless Integration in Vehicle Electronics

The TS30359-12P-11 is a purpose-built male connector designed to replace original equipment and Molex-compatible systems in automotive and marine environments. Its black housing offers a clean, professional appearance and helps prevent miswiring by providing visual differentiation from green or brown variants in complex harness setups. Designed to mate with the TS30359-12P-21 female housing, it ensures a secure, polarized connection that resists accidental disengagement. This makes it an excellent choice for OEM replacements, aftermarket upgrades, and custom wiring projects in cars, yachts, UTVs, and industrial machinery.

Mat-Sealed Technology for Superior Environmental Protection

Each terminal cavity is equipped with a pre-installed mat seal and protective diaphragm that forms a watertight seal around the wire insulation upon insertion. This advanced sealing mechanism effectively blocks moisture, dust, salt, and other contaminants from entering the connector body—critical for applications exposed to harsh conditions. Whether installed under the hood, on a boat deck, or in an off-road vehicle, this connector maintains signal integrity and prevents corrosion, ensuring long-term reliability and reduced maintenance.

Robust Two-Piece Housing with Secondary Lock

To withstand vibration and mechanical stress, the TS30359-12P-11 features a two-piece housing design with a secondary lock wedge. After Terminals are crimped and inserted, the wedge is engaged to lock all contacts in place. This dual retention system prevents terminal backout caused by engine vibration, rough terrain, or repeated thermal cycling—common challenges in automotive and marine systems. The result is a stable, long-lasting connection that supports uninterrupted signal transmission.

High-Performance Materials for Durability and Stability

The housing is constructed from either PBT+GF15% or PA66+GF30%, both of which are high-strength, glass-reinforced thermoplastics known for excellent heat resistance, impact strength, and dimensional stability. These materials ensure the connector maintains its structural integrity across a wide temperature range, making it suitable for use in extreme environments. The black color provides UV resistance and helps mask dirt and wear, preserving the connector’s appearance over time.

Versatile Terminal Options for Custom Wiring Solutions

Supporting copper alloy, brass, and phosphor bronze terminals, this connector allows users to select the best material based on conductivity, cost, and mechanical requirements. Its standardized 12-pin layout is compatible with widely available crimping tools and is commonly used in audio systems, control modules, and sensor harnesses. Whether replacing a damaged connector or building a new harness from scratch, the TS30359-12P-11 offers flexibility and reliability for professional installers and DIY enthusiasts alike.

Part of a Complete MX150 Series for Broad Compatibility

This connector is part of a comprehensive MX150 Mat-Sealed series introduced in 2022, offering multiple color options (black, green, brown) and pin configurations (4, 6, 8, 12, 16, 20) to meet diverse application needs. We also supply matching female housings (TS30359-12P-21) and individual terminals upon request.
