High-quality ring terminal from Kalitec. The roughened surface of the sleeve improves contact with the conductor and increases the tensile strength of the connection. The ring diameter of the mounting hole is 5.3 mm, corresponding to M5. The non-insulated ring terminal is solder-free and suitable for crimping. Non-insulated crimp ring terminals M5 are made of copper (Cu-ETP CWOO4A) according to UNI EN 13599 standards and are tin-plated with a minimum thickness of 3 µm. The copper connectors are stamped, soldered, and annealed. Annealing enhances the structural material properties and allows the use of the terminals even under mechanical vibrations. Crimp ring terminals M12 are used to create secure electrical connections in electrical installations, for example in homes, gardens, and garages, as well as in cars, trucks, motorcycles, and bicycles. Also suitable for receivers, speakers, motors, relays, and sound systems. Delivery includes: 10 ring terminals.
