How does it work?
1
Connector selection
The correct SHARK® connector and crimping die are chosen based on wire cross-section, shape (round or rectangular), and material (copper or aluminum). This ensures proper fit and reliable performance.
2
Crimping process
Enameled wires are placed inside the connector and compressed using a dedicated ERKO hydraulic or battery-powered press with matched dies. During pressing, the connector’s sharp teeth pierce through the enamel insulation and reach the conductor core.
3
Reliable connection
The enamel remains around the wire except at the contact points, where metal-to-metal bonding is created. This guarantees both electrical conductivity and mechanical strength. The joint is ready for direct installation without additional steps like insulation stripping, soldering, or cleaning.
The smart way to connect enameled wires

Our revolutionary technology is compatible with copper and aluminum wires, both round and rectangular, making it the most versatile solution on the market.
SHARK® technology configurator
The SHARK® technology configurator is an interactive online tool by ERKO that enables quick and precise selection of connectors for enameled winding wires (copper and aluminium).
By entering basic wire parameters, the system generates the optimal connector in just a few steps – streamlining the design process and minimizing the risk of assembly errors.
