The GBC 18.5055.00 is a 4mm banana-shaped female socket in red, designed for laboratory benches, test instruments and audio panels where a standard 4mm plug needs a clean, polarised mating point. The red colour follows the convention used for positive or live connections.

The body is moulded from ABS for impact resistance and electrical isolation, while the nickel-plated brass contact gives a low-resistance, corrosion-resistant joint. A screw-type cable fixing accepts stranded or solid leads without soldering.

Key Features

• 4mm banana female socket for standard test plugs
