Here is the professional e-commerce product description for the matching red variant of the short B1-model banana plug socket, keeping your catalog structure perfectly synchronized.
Compact Short Female 4mm Banana Plug Socket – Red (B1)
Product Overview
The Model B1 Short Female 4mm Banana Plug Socket is an ultra-compact, low-profile chassis-mount jack designed for applications where internal enclosure depth is highly restricted. As seen in the design structure of image_887ae3.jpg, it features a significantly shortened barrel and threaded termination stud compared to standard variants, allowing this component to maximize space efficiency behind the panel without sacrificing physical connection strength.
With its fully insulated red outer rim and high-conductivity internal brass sleeve, it serves as an excellent space-saving test point or positive (+) terminal for tight electronic enclosures and miniature instruments.
Key Features
-
Space-Saving Short Barrel: Ultra-short internal profile reduces enclosure depth requirements, making it ideal for shallow casing designs and crowded multi-layer PCBs.
-
Universal 4mm Compatibility: Fully compatible with all standard 4mm male banana plugs, uninsulated patch cords, and test probes.
-
Streamlined Panel Mount: Easy front-insertion or rear-lock mounting via a low-profile fastening nut and solder lug terminal, seating tightly against plastic or metal equipment walls.
-
Visual Line Identification: Solid red finish provides instant visual recognition for positive (+), VCC, or hot signal lines.
