20Pin Male Grey Automotive MX150 Mat-Sealed Connector 33482-2102 – TS30359-20P-11-1 High-Density Sealed Housing for Reliable Vehicle Wiring

The TS30359-20P-11-1 is a 20-pin male grey connector engineered for durable, sealed wire-to-wire connections in modern automotive, marine, and off-road vehicle systems. Designed as part of a precision interconnect solution, this MX150-style mat-sealed connector ensures stable electrical performance in environments exposed to moisture, dust, vibration, and thermal cycling. As the male counterpart to the TS30359-20P-21-1 female housing, it enables clean, reliable integration between factory harnesses and aftermarket electronics—ideal for audio upgrades, control modules, and auxiliary system installations in cars, yachts, and UTVs. Built with high-grade thermoplastics and corrosion-resistant Terminals, this connector delivers long-term reliability without the need for splicing or soldering.

Precision-Engineered for Seamless Integration

The TS30359-20P-11-1 is designed to meet the exacting standards of modern vehicle electronics. Its 20-pin male configuration ensures full compatibility with the corresponding female housing, allowing for a secure, polarity-correct connection that prevents misalignment during installation. The grey housing provides visual differentiation from black connectors, making it easier to identify in complex harness assemblies—especially useful in multi-connector dashboards or engine control zones. This color coding supports faster diagnostics, reduces installation errors, and enhances overall system organization.

Robust Materials for Long-Term Durability

Constructed from either PBT+GF15% or PA66+GF30%, the connector housing delivers excellent mechanical strength, dimensional stability, and resistance to high temperatures (operating range: -40°C to +120°C). These glass-fiber-reinforced thermoplastics prevent warping, cracking, or deformation under stress, ensuring a consistent fit over thousands of mating cycles. Inside, the terminals are made from high-conductivity copper alloy, brass, or phosphor bronze—materials chosen for their superior electrical performance, low contact resistance, and resistance to oxidation. This combination ensures minimal signal loss and maximum power transfer across all circuits.

Mat-Sealed Design for Environmental Protection

Unlike standard connectors, the TS30359-20P-11-1 features a mat-sealed construction that protects against water, dust, and contaminants. The integrated sealing mat contains individual diaphragms for each terminal cavity, which are pierced only when a terminal is inserted—creating a tight, waterproof seal around each conductor. This IP-level protection is essential for under-dash, under-hood, or marine applications where exposure to humidity, condensation, or road spray is common. If a terminal is removed, a sealing plug can be inserted to maintain the integrity of the unused position, preserving the connector’s overall environmental rating.

Wide Range of Automotive & Marine Applications

This connector is widely used in factory-to-aftermarket audio interface kits, where it enables a no-cut installation of new head units while preserving all original vehicle functions—such as steering wheel controls, backup camera signals, and illumination circuits. It’s also suitable for use in engine management systems, lighting harnesses, navigation modules, and auxiliary power distribution. Its compatibility with various vehicle platforms makes it a versatile choice for installers, repair shops, and OEM suppliers looking for a reliable, drop-in solution.
