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

The TS30256-35P-11 is a 35-pin black female wire-to-wire connector designed to meet the high standards of TE Connectivity’s AMPSEAL series. Ideal for use in automotive, marine, and off-road applications, this sealed connector ensures reliable electrical performance in environments exposed to moisture, dust, vibration, and extreme temperatures. Commonly used in audio systems, control modules, and power distribution harnesses for cars, yachts, and UTVs, it delivers stable signal transmission and long-term durability in demanding conditions.

Featuring a robust two-piece housing design, the TS30256-35P-11 incorporates a secondary locking mechanism that prevents terminal backout during operation. After terminals are inserted into the housing, a locking wedge is inserted across all three rows of contacts—spaced at 4.0mm pitch—to secure them firmly in place. This dual-retention system enhances connection reliability and reduces the risk of intermittent faults caused by mechanical stress or thermal expansion.

Product Specifications

High-Performance Sealed Connector Design

The TS30256-35P-11 is part of the AMPSEAL-style sealed connector series, engineered to provide environmental protection in critical wiring applications. Each circuit cavity contains a built-in sealing diaphragm that is pierced when a terminal is inserted, forming a watertight seal that prevents moisture and debris ingress. If a terminal is later removed, a dedicated sealing plug should be installed to restore the seal and maintain system integrity—ensuring long-term reliability even after service or repair.

The black housing is constructed from high-strength thermoplastic materials (PBT+GF15% or PA66+GF30%) that offer excellent resistance to heat, chemicals, and mechanical impact. This makes the connector suitable for under-hood installations, exterior lighting systems, and marine environments where exposure to harsh conditions is common. The precise mold tolerances ensure smooth mating with the TS30256-35P-21 male housing, minimizing insertion force and preventing damage during repeated connection cycles.
