Non-insulated crimp terminals S6-M in ring form. The crimp terminals of the S series are made from stamped, soldered, and annealed copper strip. The annealing process enhances the structural material properties, allowing the terminals to be used even in mechanical vibrations. Surface tinning provides corrosion protection. The sleeve is soldered. The roughened surface of the sleeve improves contact with the conductor and increases the tensile strength of the connection.
