7043Y-0.6-11/ 1-967584-3/50V / Automotive Housing for Female Terminals

This product, a high-performance automotive connector developed by TE (Tyco Electronics), is identified by the TE internal number 1-967584-3 and officially designated as 4POS MQS TAB SEALED COD A. As a specialized 4-terminal male terminal sheath, it is engineered to meet the strict performance requirements of automotive signal transmission systems, integrating advanced sealing technology, robust construction, and precise electrical performance. Tailored for wire-to-wire connections in automotive applications, this connector stands out for its reliability, durability, and versatility, making it an essential component for automotive wire harnesses, signal transmission systems, and various electrical modules that demand stable and secure connectivity.

A key specification of this connector is its nominal voltage architecture of 50 volts (V), which is specifically optimized for medium-voltage automotive signal and power transmission systems. Unlike lower-voltage connectors, this 50V design is built to handle higher electrical loads while maintaining exceptional signal integrity and power transfer efficiency, minimizing voltage drop and signal interference. This 50V rating ensures seamless compatibility with a wide range of automotive components that rely on medium-voltage power and signal transmission, including sensor modules, control units, signal converters, and auxiliary electrical systems. Its medium-voltage optimization makes it ideal for modern vehicles, where advanced electrical systems require reliable connectivity to support complex signal and power management.

Designed as a male terminal sheath, this connector is precision-manufactured to mate securely and seamlessly with compatible female connectors, forming a stable and consistent electrical connection. The male terminal sheath design incorporates high-precision terminals that ensure tight, uniform contact with female counterparts, effectively reducing contact resistance and preventing signal loss, power interruption, or intermittent connectivity issues. The sheath itself serves as a protective casing, shielding the internal terminals from minor mechanical damage during installation, handling, and vehicle operation, while also facilitating easy alignment during mating. This male configuration is particularly suited for wire-to-wire connections in automotive wire harnesses, where the connector acts as the active mating component for efficient and reliable integration.

A standout feature of this connector is its “Sealable: Yes” designation, which means it is equipped with advanced sealing technology to provide superior protection against environmental contaminants. The sealed design effectively blocks moisture, dust, dirt, road debris, and automotive fluids from entering the connection point, making it suitable for both indoor and outdoor automotive applications, including under-hood, under-chassis, and exterior installations. This sealing capability is essential for preventing corrosion, short circuits, and performance degradation, even in harsh operating conditions—ensuring long-term reliability in environments where exposure to the elements is common.

The connector operates within a wide temperature range of -40 °C to 120 °C (-40 °F to 248 °F), demonstrating exceptional thermal stability and durability in extreme environmental conditions. This temperature tolerance allows it to perform reliably in frigid winter climates, where temperatures drop well below freezing, and in the moderate to high heat of vehicle engine bays or exterior components exposed to sunlight. Whether subjected to sub-zero temperatures or intense heat, the connector maintains its structural integrity and electrical performance, preventing interruptions to critical automotive signal and power systems.

Classified under the Wire & Cable and Signal categories, this connector is specifically optimized for wire-to-wire signal transmission in automotive applications. Its design simplifies integration into automotive wire harnesses, allowing for quick and efficient assembly, while the precise terminal alignment ensures a secure connection that can withstand the vibration and movement typical of vehicle operation. The connector is compatible with a wide range of wire sizes commonly used in automotive signal systems, making it versatile enough to accommodate different wiring requirements for signal transmission and auxiliary power delivery.

In automotive applications, this connector is widely used in wire harnesses for signal transmission systems, including sensor connections, control module links, and auxiliary signal circuits. Its 4-terminal design allows it to handle multiple signal channels simultaneously, such as transmitting data from multiple sensors to a central control unit, ensuring efficient and reliable communication between vehicle components. Additionally, its sealed design makes it suitable for use in exterior components, such as lighting systems or exterior sensors, where protection against the elements is critical.

Designed with ease of use in mind, this connector features an ergonomic design that allows for quick and easy mating and unmating, reducing installation time and labor costs. The precise fit of the male terminals with female connectors ensures a secure lock, preventing accidental disconnection due to vehicle vibration or mechanical stress. The standardized design and clear labeling also simplify inventory management and replacement, making it easy for maintenance teams to identify and replace components when needed, minimizing vehicle downtime.

In summary, the TE 4POS MQS TAB SEALED COD A connector (Internal Number: 1-967584-3) is a high-performance, specialized male terminal sheath designed for 50V automotive wire-to-wire signal transmission. With its 4 terminals, sealable design, 3.1 mm centerline, -40 to 120 °C operating temperature range, and durable black housing, it is well-suited for automotive signal systems, wire harnesses, and various electrical modules. Its reliable performance, superior sealing, and versatility make it a trusted choice for automotive manufacturers and engineers seeking a high-quality connectivity solution that can withstand the demands of modern automotive electrical systems.
