35-Pin Black TE AMPSEAL Style Wire-to-Wire Connector – TS30256-35P-11 for Automotive and Marine Applications

The TS30256-35P-11 is a 35-pin black female wire-to-wire connector engineered to meet the performance standards of TE Connectivity’s AMPSEAL series. Designed for reliable signal and power transmission in harsh environments, this connector is ideal for automotive, marine (yacht), and off-road (UTV) wiring systems where resistance to moisture, vibration, and thermal cycling is critical. As the male mating counterpart to the TS30256-35P-21 housing, it enables secure, sealed connections in complex harness assemblies used in engine control modules, audio systems, lighting networks, and onboard electronics.

Built with a rugged two-piece construction, the TS30256-35P-11 features an integrated secondary locking mechanism that prevents terminal backout during operation. Once terminals are inserted into the housing, a locking wedge is engaged across all three rows of contacts—spaced on a 4.0mm pitch grid—ensuring uniform pressure and long-term contact stability. The design supports high-density wiring layouts and is compatible with copper alloy, brass, and phosphor bronze terminals for optimal conductivity and durability.

Key Product Information

Robust Design for Demanding Electrical Systems

The TS30256-35P-11 belongs to the AMPSEAL-style sealed connector family, delivering IP-level protection against dust and water ingress when fully mated. Each circuit cavity contains a molded sealing diaphragm that is pierced upon terminal insertion, forming a watertight barrier around the conductor. This ensures long-term reliability in exposed areas such as under-hood installations, exterior lighting harnesses, and marine deck wiring.

In the event a terminal is removed, a dedicated sealing plug must be installed to maintain the integrity of the seal and prevent contamination. The black thermoplastic housing provides excellent UV resistance, dimensional stability, and mechanical strength, making it suitable for both factory-fit and aftermarket upgrades. Its precision-molded structure ensures smooth mating and consistent alignment with the female housing, reducing wear and improving service life.
