XY-BNC-AL-4S: BNC Male to Dual Stackable 4mm Banana Plug Test Cord, 1.2m

The XY-BNC-AL-4S is a crucial BNC male plug test cordset designed to interface professional coaxial equipment, such as oscilloscopes and function/signal generators, with standard electronic circuitry that uses 4mm banana jack connections. This cable acts as a breakout lead, translating the BNC coaxial signal into two discrete 4mm connections (typically one for the signal center conductor and one for the shield/ground).

This cord features a durable BNC Male connector on one end and two high-quality 4mm stackable banana plugs on the other. The stackable feature of the banana plugs allows multiple test leads to be connected to the same measuring point, increasing the flexibility of your testing setup. The entire assembly is constructed using 50 coaxial cable (often RG58 type) to ensure signal integrity and proper impedance matching for most test equipment applications. Its generous 1.2-meter length provides ample reach for bench work.

Key Features

• BNC to Dual Banana Conversion: Converts a standard BNC output into two separate 4mm connections (signal and ground).
• 4mm Stackable Plugs: The dual banana plugs are stackable, allowing for convenient daisy-chaining of additional test leads or accessories (e.g., probes, alligator clips) to the same points.
• Coaxial Cable: Typically uses RG58 50 coaxial cable, which ensures proper impedance matching when connecting to 50 rated test equipment (like oscilloscopes and function generators) for accurate high-frequency signal measurements.
• Generous Length: 1.2 meters (approx. 47 inches) provides flexible positioning of instruments and test circuits on a workbench.
• Applications: Ideal for use with oscilloscopes, signal generators, frequency counters, and other BNC-interface test and measurement devices to connect to circuit boards, breadboards, and power supplies.

Specifications (XY-BNC-AL-4S)

• Model Number: XY-BNC-AL-4S
• Product Type: Test Cordset / Breakout Cable
• Connector A: BNC Male Plug
• Connector B: 2 x 4mm Stackable Banana Plugs (Typically Red for Signal, Black for Ground)
• Cable Type: Coaxial (often 50 RG58 or similar soft coaxial cable)
• Cable Length: 1.2 meter
• Maximum Voltage Rating (CAT I): 500V (For measurements performed on circuits not directly connected to the mains supply, or protected electronic circuits).
• Maximum Current Rating (CAT II): 3A
• Maximum Voltage Rating (CAT II): 150V (For measurements performed on household appliances, portable tools, and similar equipment).
• Insulation Material: PVC (Polyvinyl Chloride) or similar.

Safety and Rating Notes

The cable is rated for CAT I: 500V and CAT II: 150V/3A.

• CAT I (Measurement Category I): Refers to measurements on circuits not directly connected to the main supply (e.g., low-voltage electronic circuits, battery-operated devices). The voltage rating is 500V peak.
• CAT II (Measurement Category II): Refers to measurements on circuits connected directly to the low-voltage installation (e.g., household appliances, portable tools, outlets). The rating is 150V with a 3A current limit.

Due to the nature of BNC connections and the non-shrouded design typical of many 4mm banana plugs on these leads, this cordset is not suitable for high-energy or high-voltage installations (CAT III or CAT IV environments).
