Banana Plug Female 4mm D:11mm
The Banana Plug Female 4 mm D:11 mm is a compact panel-mount socket designed to accept standard 4 mm male banana plugs. Housed in an insulating plastic shell with a durable metal contact inside, the connector offers a secure, low-resistance electrical junction when mated. Its small size with a socket diameter of 4 mm and an 11-mm depth makes it suitable for tight enclosures and compact test rigs, enabling tidy wiring and stable connections without bulky hardware.
When installed (often in a panel or instrument enclosure), the socket serves as a reliable interface: it holds the male banana plug firmly, thanks to a spring-metal or slotted internal contact that grips the plug’s 4 mm pin. This ensures consistent electrical contact over repeated insertions and removals. The insulating housing prevents accidental shorts and allows for safe handling even when the socket carries current.
Because of its standard sizing and mounting-friendly design, this female banana plug fits into a wide variety of equipment from lab test benches and power supplies to DIY electronics projects and audio or instrumentation panels. Its panel-mount form factor keeps the connector fixed securely, giving a durable and stable interface that can withstand repeated connections. The simplicity, standardization, and reliability make it a convenient choice for anyone needing removable, reusable, and safe connectors for low-voltage or test-equipment wiring.
