RS PRO Uninsulated Ring Terminal, M4 Stud Size, 0.5 mm² to 1.5 mm² Wire Size


Use this RS PRO copper ring terminal with a brazed seam to create a solid connection between wires and a connection point. The copper contact material is known for being highly conductive, so you can be sure of stable connections. It's also extremely durable, so you're assured a long-lasting product. It's an uninsulated type terminal, so it's suitable for areas where a solder joint is needed. This feature is also beneficial because it enhances heat resistance, which in turn helps to prevent short circuits.
This ring terminal is extremely easy to install and requires nothing more than a crimper. In addition, it has a flexible allowance for wire sizes between 0.5 mm and 1.5 mm, so you're not limited to a particular cable diameter. Typical applications for components such as this one include wiring in industrial machinery and control systems.
