Product Detail

This DB9 to Banana Plug test cable is designed for rapid connection in automotive electronics R&D, ECU debugging, and laboratory measurement. It converts a standard 9-pin D-Sub (DB9) interface into two individual banana plug test points, facilitating immediate connection to multi-meters, oscilloscopes, or power supplies .

Accurate Specifications

  • Connector A: 1x Standard DB9 Female socket (with thumb screws).
  • Connector B: 2x 4.0mm Banana Plugs (Red for positive/power/High, Black for ground/Low) .
  • Cable Construction: Durable black PVC jacket with high-grade copper cores (typically 22AWG) .
  • Length: 100cm (1m) .
  • Shielding: Features multiple protective shields to minimize electromagnetic interference (EMI) during signal measurement .

Key Features & Benefits

  • Precise Wiring: The red and black dual banana plugs provide a clear visual distinction for power and ground lines, allowing for quick identification and patching into test equipment .
  • Stable Data Transfer: The full shielding structure ensures accurate and stable transmission for signals (such as CAN-High, CAN-Low, or power lines) in research, testing, and validation processes .
  • ECU Diagnostics Support: Essential for checking ECU power supply and verifying whether the 60-ohm termination resistor is correctly connected .
  • Plug & Play Flexibility: Ideal for setting up test circuits in lab environments, allowing for quick connections to oscilloscopes, breakout boards, or bench power supplies
