7048C-1.5-21/776487-1/12V/24V /48V/ Automotive Housing for Female Terminals

The TE Internal Number 776487-1 refers to a high-performance, sealed automotive plug assembly belonging to TE Connectivity’s renowned AMPSEAL 16 product series, a line specifically engineered to meet the rigorous demands of heavy-duty industrial and automotive applications. This plug assembly is designed with precision and durability in mind, incorporating advanced manufacturing techniques and high-quality materials to ensure reliable electrical connectivity even in the harshest operating environments—such as those with extreme temperature fluctuations, heavy vibration, and exposure to corrosive substances. Its robust design makes it an ideal choice for a wide range of vehicle and industrial systems, where consistent performance and long service life are non-negotiable requirements.

Officially described in TE’s internal documentation as AS16, PLUG ASSY, ST, 04P, N SEAL, CODE A, this product is also identified by its Alias ID 8202613540 and the part number AS16-ST-06-04SA-N, providing multiple reference points for inventory management, procurement, and technical verification. As a key component of the AMPSEAL 16 series, it inherits the series’ signature ruggedness and sealing capabilities, which are critical for applications exposed to moisture, dust, vibration, and extreme temperatures.

In terms of electrical specifications, the 776487-1 plug assembly features a versatile Nominal Voltage Configuration that supports 12V, 24V, 48V, and 240V, making it compatible with a diverse array of electrical systems—from standard automotive circuits to higher-voltage industrial equipment. This voltage flexibility allows it to be integrated into various applications, including off-road vehicles, heavy-duty trucks, agricultural machinery, and industrial control systems, where different voltage requirements may exist within a single setup.

The connector and housing type is a plug, with a 4-position (4-bit) design that enables secure, low-resistance wire-to-wire connections. The centerline spacing of 5.3 mm (0.209 inches) is carefully optimized for compact installation, allowing it to fit into tight spaces within vehicle engine compartments or industrial equipment while ensuring sufficient space for wire routing and insulation. This thoughtful design reduces the risk of short circuits or signal interference, which can lead to system malfunctions or equipment failure. The plug is constructed in a sleek black finish, which not only enhances its aesthetic integration with various systems but also provides an additional layer of protection against environmental wear and tear, including UV radiation and minor chemical exposure.

A standout feature of the 776487-1 is its sealable design, marked as “Sealable: Yes,” which ensures an IP67-rated protection level against dust and water ingress. This sealing capability is achieved through high-quality silicone rubber wire seals and peripheral seals, preventing moisture, dirt, and other contaminants from entering the connector and compromising electrical performance—critical for applications in engine compartments, under-chassis routing, or outdoor industrial settings.

The operating temperature range of -40 °C to 125 °C (-40 °F to 257 °F) further underscores its durability, allowing it to function reliably in extreme cold and high-heat environments, such as freezing winter conditions or near-engine installations where temperatures can rise significantly. This temperature resilience is supported by the connector’s housing material—15% glass-filled thermoplastic—which offers excellent thermal stability and mechanical strength.

Internally, the plug uses Heavy Duty Stamped & Formed (HDSF) size 16 contacts, rated for up to 13 amps per circuit, which can accommodate wire gauges ranging from 14 to 20 AWG (0.50 to 2.50 mm²). These contacts feature a lanceless design with dual beams, ensuring secure contact retention and reducing the risk of contact back-out, even under high vibration conditions—tested to withstand 21 g RMS vibration between 25 to 2000 Hz.

As a wire-to-wire connector, the 776487-1 is part of TE’s Wire & Cable product lineup, specifically designed to facilitate efficient and reliable connections between wire harnesses in complex electrical systems. Its one-piece fully assembled housing streamlines the installation process, reducing labor time and minimizing the risk of loose parts or improper assembly. Additionally, integrated Connector Position Assurance (CPA) and Terminal Position Assurance (TPA) features provide visual and tactile confirmation that the connector is properly latched and terminals are correctly seated, preventing accidental unlatching and ensuring consistent electrical performance. This plug is widely used in critical applications such as automotive motors, gearboxes, ABS/EBS systems, hydraulic pumps, industrial sensors, and on-engine control units, embodying TE Connectivity’s commitment to delivering high-reliability components for the most demanding industrial and automotive environments.
