This product, part of TE’s renowned AMPSEAL 16 series, is identified by the TE internal number 776535-1 and officially designated as AS16,CAP ASSY,ST,03P,E SEAL,CODE A, with an alias ID of AS16-ST-04-03PA-E. It is a high-performance, industrial-grade wire-to-wire cap assembly connector engineered to deliver exceptional reliability and durability in the most demanding automotive and industrial applications. Designed with TE’s cutting-edge technology and strict quality control standards, this 3-position connector stands out for its superior sealing capabilities, wide voltage compatibility, and robust construction, making it a preferred choice for engineers and manufacturers seeking a versatile and long-lasting connectivity solution.

One of the key highlights of this connector is its wide nominal voltage architecture, which supports 12V, 24V, 48V, and 240V, making it highly versatile and compatible with a broad range of low-to-medium voltage electrical systems. This multi-voltage compatibility allows the connector to be seamlessly integrated into various applications, from automotive electrical systems and industrial machinery to heavy-duty equipment, eliminating the need for multiple connector types and reducing inventory costs. Whether powering small automotive components at 12V or supporting higher-voltage industrial setups at 240V, this connector maintains stable electrical performance, ensuring consistent power transmission and signal integrity.

The connector features a female terminal design, which provides optimal protection for internal electrical contacts while ensuring a secure, snug mating with compatible male connectors. The female terminal configuration is engineered to prevent accidental disconnection, minimize contact resistance, and shield internal components from external contaminants. This design not only enhances the connector’s electrical performance but also extends its service life by reducing the risk of corrosion, short circuits, and signal interference, even in harsh operating conditions.

Equipped with 3 positions (pins), this cap assembly is specifically configured for wire-to-wire connections, with a 4.5 mm (.177 in) centerline that ensures precise alignment and efficient power transfer. The 3-pin design allows for the transmission of power, control signals, or a combination of both, making it suitable for a wide range of applications, including automotive wire harnesses, industrial control systems, and heavy-duty equipment wiring. The precise centerline measurement ensures that the connector mates perfectly with compatible components, reducing installation time and minimizing the risk of misalignment.

Marked as “Sealable: Yes” in the product specifications, this connector boasts excellent waterproof and dustproof capabilities, thanks to its advanced E SEAL design. The sealable construction effectively prevents moisture, dust, dirt, and other contaminants from entering the connection point, making it ideal for outdoor applications or environments with high humidity, dust, or exposure to liquids. This sealing feature is particularly critical for automotive applications, where connectors may be exposed to rain, snow, road debris, and extreme temperature fluctuations, ensuring reliable performance in all weather conditions.

The connector operates within an extensive temperature range of -40 °C to 125 °C (-40 °F to 257 °F), demonstrating exceptional thermal stability and durability in both extreme cold and high-heat environments. This wide operating temperature range makes it suitable for use in automotive under-hood applications, industrial furnaces, outdoor renewable energy systems, and other environments where temperature variations are significant. Even at the extreme ends of this range, the connector maintains its structural integrity and electrical performance, ensuring uninterrupted operation.

Constructed from high-quality, durable nylon material, the connector’s housing offers superior mechanical strength, impact resistance, and chemical resistance. Nylon is known for its excellent durability, ability to withstand harsh chemicals, and resistance to wear and tear, making it an ideal material for automotive and industrial connectors. The black housing not only provides a sleek, professional appearance but also offers additional protection against UV radiation, preventing discoloration and degradation when exposed to sunlight for extended periods.

Designed specifically for wire harness cable applications, this AMPSEAL 16 connector is optimized for easy integration into automotive wire harnesses, ensuring a secure and reliable connection between wires. Its wire-to-wire configuration simplifies installation, allowing for quick and efficient assembly, while the robust housing protects the internal terminals from mechanical damage during installation and daily use. The connector is compatible with a wide range of wire sizes, making it versatile enough to accommodate different wiring requirements in various applications.

In automotive applications, this connector is widely used in wire harnesses for engines, transmissions, lighting systems, and other critical components. Its waterproof and temperature-resistant design ensures reliable performance even under the harsh conditions of under-hood environments, where exposure to heat, vibration, and moisture is common. In industrial settings, it is used in control systems, heavy machinery, and equipment wiring, providing a secure connection that can withstand the rigors of industrial operation.

In summary, the TE AMPSEAL 16 connector (Internal Number: 776535-1; Alias ID: AS16-ST-04-03PA-E) is a versatile, high-performance wire-to-wire cap assembly that combines wide voltage compatibility, superior sealing, and robust construction. With its 3 positions, female terminal design, sealable feature, -40 to 125 °C operating temperature range, and durable nylon housing, it is well-suited for a wide range of automotive and industrial applications. Whether used in automotive wire harnesses, industrial control systems, or heavy-duty equipment, this connector delivers consistent, reliable performance, making it a trusted choice for engineers and manufacturers worldwide.
