2 Product Overview
The tinned copper cable ring terminals are designed for reliable compression termination of copper conductors in low-voltage power distribution and control applications. Available from 10 mm² to 630 mm² with DIN-standard dimensions, these terminals provide secure, low-resistance connections.
Manufactured from high-purity electrolytic copper with a full tin-plated finish, each terminal offers excellent corrosion resistance and stable contact performance over the service life. The seamless tubular barrel ensures uniform compression, while the ring palm is designed for secure bolting to busbars, switchgear, and equipment terminals.
These terminals are widely used in EV charging station installations, power distribution panels, motor control centres, and industrial electrical systems where reliable cable termination is critical. Compliance with DIN standards ensures compatibility with standard crimping tools and dies.
Manufactured to rigorous quality standards under the management of SORIVO, each batch is tested for dimensional accuracy, material purity, and crimping performance. For detailed company information, please visit sorivocable.com/about-us/.

5 FAQ
What is the difference between DIN 46234 and DIN 46235 terminals?
DIN 46234 covers ring-type terminals (solderless) with a thinner palm section, while DIN 46235 covers tubular compression lugs with a thicker barrel and palm. Both are suitable for crimping; the choice depends on the conductor class and application.
Are these terminals suitable for EV charging station wiring?
Yes, these tinned copper terminals are widely used in EV charging stations for power cable termination. The tin-plated finish provides corrosion resistance, and the high-purity copper ensures efficient power transfer for high-current charging applications.
What crimping tool do I need?
These terminals require a hydraulic or manual crimping tool with hexagonal dies matching the barrel diameter. Use hexagonal compression dies per DIN 48083-4 for best results. The die size must match the terminal barrel outer diameter after crimping.
Do you offer free samples?
Yes, free samples are available for qualified projects and OEM customers. Contact SORIVO with your requirements, and we will arrange sample shipment for evaluation and testing.
Can I get terminals with specific bolt hole sizes?
Yes, each cable cross-section is available with standard bolt hole sizes as listed in the specifications. Custom bolt hole diameters and non-standard palm configurations can be manufactured for volume orders.
