RS PRO Uninsulated Tubular Ring Terminal M8 Stud Size 4 AWG Wire Size Grey 531-071

RS PRO 531-071 uninsulated tubular ring terminal is engineered for dependable electrical connectivity in industrial and heavy-duty electrical systems. Designed specifically for an M8 stud size with a 4 AWG wire size, this grey ring terminal is constructed from highly conductive copper, plated with tin to provide resistance against corrosion and enhanced solderability. The thick-walled tubular design ensures a robust mechanical and electrical connection when crimped correctly.

The tubular barrel shape is funnel-shaped internally, which facilitates easy wire insertion, and the closed barrel secures the connection around the wire. This terminal is suitable for multi-stranded cables and is widely used in applications such as industrial control systems, automotive wiring, power supplies, communication equipment, and domestic appliances where a secure crimped connection to a stud or post is required.

Key specifications include an outer ring diameter of 13.1 mm, inner ring diameter of 8.4 mm, overall length of 32.2 mm, and a maximum wire size of 4 AWG (25 mm²). The terminal is rated for maximum operating temperatures up to 150°C, complying with RoHS and ANSI/ESD S20.20:2021 electrostatic standards, ensuring safety and performance in electrostatic-sensitive environments.

The uninsulated design is appropriate where there is no risk of short circuits through accidental contact. Suitable crimping tools include heavy-duty handheld and hydraulic crimp tools, ensuring secure and consistent crimps. The product is manufactured in China, reflecting high quality standards.
