RS PRO Uninsulated Ring Terminal 5.3 mm Stud Size, 12 AWG to 10 AWG, Copper, Tin Plated, Grey 178-8619

RS PRO 178-8619 Uninsulated Ring Terminal is engineered for secure crimped electrical connections in electronics, industrial wiring, and automation panels. With a stud size of 5.3 mm, this terminal accommodates wire gauges from 12 AWG to 10 AWG, making it ideal for a broad range of installations. The contact material is copper, providing excellent conductivity, and is tin plated for enhanced corrosion resistance and durability. The product features an outer ring diameter of 9.5 mm and an inner diameter of 5.3 mm, ensuring a precise fit for compatible connectors or terminal blocks. Its robust construction guarantees lasting performance even under demanding industrial, commercial, and manufacturing conditions.

This terminal is finished in grey and lacks insulation, making it suitable for applications where insulation is provided elsewhere or not required. It is capable of supporting wire cross-sections from 4 mm² (minimum) to 6 mm² (maximum) and withstands operating temperatures from -40°C up to 150°C, suitable for both cold and hot environments. Measuring 19 mm in length and 1 mm in thickness, the terminal is designed for ease of installation and effective crimping, while the high quality standards ensure compatibility and reliability.

RS PRO ring terminals are widely used in circuit connections, panel wiring, control cabinets, and machinery setups requiring robust and maintenance-friendly crimp solutions. Applications include power distribution panels, industrial controls, laboratory instruments, and commercial electrical installations.

The copper contact, tin plated surface, and well-defined mechanical dimensions provide excellent connection integrity and minimize resistance, making these terminals a preferred choice for electrical engineers and professionals working in automation, HVAC, water treatment, and electronics assembly.

For bulk installations or panel build-outs, these terminals are available in convenient packs, supporting efficient component management. Complies with relevant industrial safety and performance standards.

Uninsulated ring terminal fits 5.3 mm studs for standard crimp applications. Copper contact with tin plating ensures low resistance and long-term reliability. Wide ambient temperature operation from -40°C to 150°C. Accommodates wire gauges 12 AWG through 10 AWG, supporting cross-sections up to 6 mm².
