23Pin Black TE AMPSEAL Connector Wire-to-Wire Connector – Ruggedized Sealed Housing TS30256-23P-11 for Automotive & Marine Applications

The TS30256-23P-11 is a high-integrity 23-pin black female connector designed for reliable wire-to-wire connections in harsh environments. As the male mating counterpart to the TS30256-23P-21, this AMPSEAL-style connector is part of a trusted sealed series engineered for automotive, marine, and off-road vehicle systems where durability and environmental resistance are critical. Whether used in engine bays, underbody harnesses, or onboard yachts and UTVs, it ensures stable electrical performance even under extreme vibration, moisture, and temperature fluctuations. Built with precision-molded thermoplastic and robust metal contacts, this connector delivers long-term reliability for both OEM integration and aftermarket upgrades.

Engineered for Harsh Conditions – Sealed & Vibration-Resistant

The TS30256-23P-11 is not just another wire-to-wire connector—it’s a fully sealed, industrial-grade solution built to survive the toughest conditions. Each cavity in the housing contains a protective diaphragm within the mat seal that is only broken when a terminal is inserted, creating a watertight and dustproof barrier around each contact. This prevents corrosion, short circuits, and signal degradation caused by exposure to rain, salt spray, or road grime. If a terminal is later removed, a sealing plug can be installed to maintain the integrity of the unoccupied position—ensuring the entire connector remains protected.

In addition to its environmental sealing, the connector features a two-piece housing system with a secondary locking wedge. After terminals are inserted into the main body, the locking wedge is slid into place, applying uniform pressure to secure every contact. This prevents terminal backout due to thermal expansion, mechanical shock, or constant vibration—common issues in automotive and marine applications. The result is a connection that stays solid mile after mile, even on rough terrain or rough seas.

Optimized 3-Row 4.0 mm Grid for Dense Signal Routing

With 23 circuits arranged in a three-row configuration on a 4.0 mm centerline grid, the TS30256-23P-11 offers a compact yet highly functional design ideal for modern vehicle electronics. This layout supports complex signal routing—including power, ground, audio, data, and control lines—in a single, organized interface. The symmetrical structure ensures balanced mechanical stress during mating, reducing wear and extending service life. Its compatibility with standard AMPSEAL tools and terminals makes it easy to assemble, test, and repair in the field.

Widely Used in Automotive, Marine & Off-Road Systems

This connector is commonly found in engine control modules, lighting harnesses, transmission sensors, infotainment systems, and auxiliary power units. Its black PBT or PA66 housing blends seamlessly with factory wiring looms, making it a preferred choice for professional installers and OEMs alike. Whether you're upgrading a car stereo, replacing a damaged harness, or building a custom UTV control system, the TS30256-23P-11 provides a clean, plug-and-play solution that eliminates the need for splicing or soldering.
