Non-insulated crimp terminals S10-M in ring shape. The crimp terminals of the S series are punched from copper strip, soldered, and annealed. The annealing process enhances the structural material properties and allows the terminals to be used even under mechanical vibrations. A tinning of the surface provides protection against corrosion. The sleeve is soldered. The roughened surface of the sleeve improves contact with the conductor and increases the tensile strength of the connection.
