Cliff Electronics Launches Switching 4mm Banana Socket
In March 2026, Cliff Electronics introduced the FCR7370 switching 4mm banana socket, a right-angle PCB-mount component engineered for high-voltage applications and laboratory-grade robustness .
Key Technical Specifications:
Parameter | Rating |
|---|---|
Voltage Rating | 1kV (CAT III) |
Current Rating | 10A |
Contact Finish | Gold-plated |
Mounting | Right-angle PCB-mount |
Protection | Fully shrouded design |
Innovative Switching Mechanism:
Inside the socket are two fixed, insulated internal contacts. When a 4mm banana plug is inserted, it bridges the two contacts, creating the electrical connection. There is no internal mechanical switching mechanism—the switching occurs solely through the physical insertion of the plug, enabling straightforward circuit routing, signal enabling, load switching, or safety interlock functions without additional switches or electromechanical parts. This simplified approach reduces component count, eases system design, and supports long-term reliability in demanding technical environments .
Applications:
Automatic enable/disable or load-switch points
Bench-top and portable instrumentation
Training, laboratory, and educational equipment
Calibration and diagnostic interfaces
Multi-channel measurement or colour-coded test systems
The FCR7370 is available in four standard colours: red, black, green, and blue, providing clear channel identification on dense panels or PCBs .
