The 35-Position Wire-to-Board Connector 776164-4 is a premium waterproof automotive connector designed for harsh automotive environments. Part of Tyco’s AMPSEAL line, this female terminal housing bridges the gap between wires and circuit boards, delivering reliable signal and power transmission in engine bays, undercarriages, and other exposed locations. Its gray PBT GF material housing offers exceptional durability, while the integrated sealing system meets IP67 standards for waterproof and dustproof protection. With 35 positions, it supports complex wiring harnesses, making it ideal for engine control units (ECUs), sensor arrays, and actuator systems in modern vehicles. The connector’s tool-less installation and wedgelock feature ensure secure assembly and maintenance.
The ECU is the "brain" of a vehicle, requiring secure connections to sensors, actuators, and other components. This wire-to-board connector provides a sealed interface between the ECU’s circuit board and the vehicle’s wiring harness, protecting sensitive electronics from oil, coolant, and debris. Its 35-position configuration supports multiple signal and power lines, enabling the ECU to communicate with engine sensors, fuel injectors, and ignition systems.
Off-road vehicles, ATVs, and heavy-duty equipment operate in extreme conditions—mud, water, rocks, and intense vibration—demanding connectors that can withstand abuse. The IP67 waterproof connector design of this housing ensures reliable performance in these environments, preventing water and debris from damaging contacts. It is also vibration and shock-resistant, making it suitable for use in construction equipment, agricultural machinery, and military vehicles.
The connector’s waterproof design features integrated seals that prevent water ingress even when submerged, meeting IP67 standards. This level of protection is critical for automotive applications exposed to rain, snow, and washdowns, extending the life of both the connector and the circuit board it powers. The sealing system is easy to inspect and maintain, ensuring long-term reliability.
Equipped with an integrated latch for mating and a wedgelock system, the connector ensures a secure, vibration-resistant connection that won’t disengage during operation. The wedgelock confirms contact alignment and retention, eliminating the risk of terminal backout and electrical faults. This dual-security system is essential for high-stress automotive applications where connector failure could lead to costly downtime.
The connector uses copper alloy contacts with gold or tin plating, optimizing conductivity and corrosion resistance. Gold plating supports higher current capacity and lower resistance, while tin plating offers cost-effective reliability for standard applications. The 1.3mm contact size balances current-carrying capacity with compact design, making it suitable for both signal and low-power applications.
Crafted from PBT GF (polybutylene terephthalate with glass fiber), the housing combines strength, flexibility, and chemical resistance. It withstands exposure to automotive fluids, UV radiation, and extreme temperatures, maintaining its structural integrity in harsh environments. The rectangular shape allows for compact installation on circuit boards, with dimensions optimized to fit standard ECU and sensor housings.
The connector features tool-less backshell accessories that simplify installation and reduce wire strain, eliminating the need for specialized tools. The gray color provides high visibility for easy identification in complex wiring harnesses, while the clearly marked positions facilitate quick assembly and troubleshooting. It is serviceable, allowing for terminal replacement and maintenance without replacing the entire connector.
We offer OEM/ODM services to meet the unique needs of automotive manufacturers, including custom contact configurations, modified housing dimensions, and branded packaging. Our engineering team collaborates with customers to design connectors that integrate seamlessly into their specific systems, from concept development to mass production. We also provide compliance testing and certification to meet regional automotive standards.
All connectors come with a 3-year warranty, covering defects in materials and workmanship. Our after-sales service includes online technical support, troubleshooting assistance, and replacement parts for faulty units. We also offer training programs for assembly and maintenance teams, ensuring optimal use of the connector and minimizing downtime. For large-scale orders, we provide dedicated account managers to oversee production, delivery, and support.
