The innovative SB® connectors provide cost-effective reliability, design flexibility and safety for your products' manufacture, installation, and maintenance. There are SB® connectors for many applications and wire sizes. We stock #6 to #12 AWG (13.3 to 1.3 mm²). Mechanical keys ensure connectors will only mate with connectors of the same color. Different color housings are selected to identify voltages, thus preventing mismatching of the power supply system.
