In the realm of industrial connectivity, TE Connectivity has long been a benchmark for quality and performance, and the TE 281838-4 terminal wire stands as a prime example of the brand’s commitment to innovation and reliability. As part of the AMPMODU HE13/HE14 product series—a widely recognized signal standard for automation and control applications—this 4-way terminal wire combines precision engineering, durable materials, and versatile design to meet the demanding requirements of modern industrial systems.
Core Technical Specifications
At the heart of the TE 281838-4 lies a set of well-defined technical parameters that ensure consistent performance across applications. The terminal wire features a single-row configuration with 4 contacts and a standard pitch of 2.54 mm, a universal spacing that enables seamless compatibility with most industry-standard shrouded headers and interconnect components . Its female socket design adopts a straight body orientation, with dimensions measuring 10.16 mm in length, 5.08 mm in width, and 15 mm in height, making it compact enough for space-constrained installations while maintaining structural integrity .
The housing is constructed from glass fiber-reinforced PBT (polybutylene terephthalate), a material renowned for its excellent mechanical strength, resistance to heat and chemicals, and long-term durability—critical properties for harsh industrial environments . The blue-colored housing not only aids in visual identification during assembly but also adheres to TE’s strict quality control standards. For wiring compatibility, the terminal wire accepts 24 AWG to 28 AWG discrete wires and works seamlessly with crimp terminals (e.g., TE part number 532-456), featuring an access window for easy terminal removal and maintenance .
Electrical performance is equally impressive: the TE 281838-4 supports a nominal current rating of up to 3A (with some sources citing 5A for specific use cases) and a nominal voltage of 500V, ensuring stable signal transmission and power delivery for control circuits and low-power applications . The contacts are made of high-conductivity copper alloy with tin plating, enhancing electrical connectivity while preventing corrosion and ensuring long-term reliability .
Key Features and Advantages
One of the standout features of the TE 281838-4 is its secure locking mechanism, designed to locate and lock firmly with shrouded headers, minimizing the risk of accidental disconnection due to vibration or mechanical stress— a common concern in industrial automation settings . The cable mount (free-hanging) installation type offers flexibility in routing, allowing engineers to integrate the terminal wire into complex system layouts without compromising stability .
Economical and reliable, the AMPMODU HE13/HE14 series—including the 281838-4—has become a go-to choice for cost-sensitive projects that demand uncompromised performance. Its compatibility with both discrete wires and ribbon cables (via IDC receptacle assemblies) adds to its versatility, enabling use in a wide range of interconnect configurations . Additionally, the terminal wire holds an MSL (Moisture Sensitivity Level) rating of 1, meaning it has no shelf-life restrictions related to moisture exposure, simplifying inventory management for manufacturers and distributors .
Compliance with global standards is another key advantage. The TE 281838-4 is lead-free and fully RoHS (Restriction of Hazardous Substances) compliant, aligning with environmental regulations worldwide and making it suitable for use in eco-conscious industries . It also bears the mark of TE’s rigorous quality assurance processes, with origin tracing to Poland, ensuring consistency in manufacturing standards .
Applications and Industry Relevance
The TE 281838-4 terminal wire is engineered for the unique demands of automation and control systems, where reliable signal transmission is critical to operational efficiency. Its applications span across multiple industries, including industrial machinery, robotics, HVAC systems, medical equipment, and consumer electronics. In factory automation, for example, it serves as a key interconnect component in sensor networks, control panels, and programmable logic controllers (PLCs), facilitating seamless communication between devices.
Beyond industrial settings, the terminal wire’s compact design and robust performance make it suitable for electronic devices requiring secure, space-efficient connections—such as test equipment, instrumentation, and IoT (Internet of Things) devices. Its compatibility with standard industry components also simplifies system integration and reduces downtime during maintenance or upgrades, a valuable benefit for end-users seeking to optimize operational productivity.
Conclusion
As a core member of TE Connectivity’s AMPMODU HE13/HE14 series, the TE 281838-4 terminal wire embodies the perfect balance of reliability, versatility, and cost-effectiveness. Its precision engineering, durable materials, and compliance with global standards make it an ideal choice for industrial automation and control applications, where performance and longevity are non-negotiable. Whether used in complex factory systems or compact electronic devices, this terminal wire delivers consistent, secure connectivity that engineers and manufacturers can trust. For those seeking a proven interconnect solution that meets the demands of modern industry, the TE 281838-4 stands as a testament to TE Connectivity’s legacy of excellence in connectivity technology.
