Engineered for Secure, Vibration-Resistant Automotive Connections

The TS30381-12P-11 male housing is built to withstand the harsh conditions found in automotive environments. Whether mounted in an engine compartment, integrated into a dashboard control module, or used in marine and off-road applications, this connector maintains stable electrical performance under continuous vibration, temperature fluctuations, and exposure to moisture and dust. Its male design ensures compatibility with the TS30381-12P-21 female housing, forming a sealed, interlocked interface that resists accidental disconnection and environmental degradation.

Robust Two-Piece Design with Secondary Locking

Unlike basic connectors that rely solely on terminal latches, the TS30381-12P-11 features a two-piece housing system that incorporates a secondary locking mechanism. After Terminals are inserted, a locking wedge is engaged to secure all contacts in place. This dual retention system prevents terminal backout caused by engine vibration or mechanical stress, significantly reducing the risk of intermittent faults and system failures in critical automotive circuits.

Integrated Mat Seals for Superior Environmental Protection

Each terminal cavity includes a molded mat seal with a protective diaphragm. When a terminal is inserted, the diaphragm is pierced, creating a watertight seal around the wire insulation. This prevents moisture ingress, dust accumulation, and corrosion—common causes of electrical failure in vehicle systems. If a terminal is later removed, a sealing plug must be installed to restore the cavity’s protection, ensuring the housing remains fully sealed and functional over time.

High-Performance Materials for Long-Term Durability

Manufactured from either PBT+GF15% or PA66+GF30%, the housing offers excellent resistance to heat, impact, and chemical exposure. These glass-reinforced thermoplastics maintain structural integrity across a wide temperature range, making them ideal for under-hood and industrial applications. The black finish provides UV resistance and aesthetic consistency, blending seamlessly with factory-installed components in cars, yachts, and UTVs.

Compatible with Standard Terminals and Harness Configurations

The TS30381-12P-11 accepts a variety of terminal types, including copper alloy, brass, and phosphor bronze, allowing for customization based on conductivity, cost, and mechanical requirements. Its 4.0mm pitch and 12-way layout support organized, high-density wiring suitable for audio systems, sensor arrays, and power distribution modules. The standardized design ensures compatibility with existing tooling and assembly processes, making it easy to integrate into both OEM and aftermarket production lines.

Ideal for Diverse Automotive and Industrial Applications

Typical uses include:

• Replacement connectors for factory-installed audio and infotainment systems

• Engine management and sensor harnesses in passenger and performance vehicles

• Marine control panels and navigation system wiring in yachts and boats

• Electrical interfaces in UTVs, ATVs, and agricultural equipment

• Custom wiring solutions for OEM upgrades and retrofit installations

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

Our Automotive connectors are components of a vehicle's electrical system that allow power, electrical signals and data to be safely and reliably transmitted between respective systems. Connectors are often used to link the main power supply, wherever the engine is located, to all the other electrical systems within the vehicle. These systems can include brakes, transmission, steering and climate control. Different types of automotive connectors are used for different purposes, and the style, number and location of connectors can vary depending on the make and model of the vehicle. Automotive connectors can include connectors for devices such as headlamps, sensors, lights, power tools, and other devices that may be built in to the vehicle. They are usually designed for use in an automotive environment, and as such must be able to withstand all the extreme conditions that driving may present.
