Overview

TE Connectivity 8-33470-2 is a closed barrel ring tongue terminal designed for high-reliability power and signal transmission in industrial environments. This uninsulated terminal features a 4 AWG wire compatibility and a 5/16" (8.33 mm) M8 stud size, making it ideal for secure connections to motors, transformers, and control panels. The closed barrel design ensures a tight, vibration-resistant grip on stranded conductors, preventing wire pull-out and maintaining consistent electrical contact under mechanical stress. Tin plating provides corrosion resistance and compatibility with copper conductors, extending service life in harsh conditions. With a straight orientation, this terminal simplifies installation in tight spaces while supporting high-current applications up to the wire's rated voltage. Commonly used in industrial machinery, automation systems, and heavy-duty equipment, the 8-33470-2 delivers dependable performance where electrical integrity is critical. Its robust construction and precise engineering make it a cost-effective solution for both new installations and maintenance operations. The terminal's design aligns with standard industrial practices, ensuring compatibility with existing tooling and infrastructure.
