9V Battery Connector with DC Jack

Specification

1. Connector Type:
   • Battery Connector: 9V snap-on style (compatible with rectangular 9V batteries).
   • DC Jack: Male or female DC power plug (usually 5.5mm outer diameter and 2.1mm inner diameter).
2. Electrical Characteristics:
   • Voltage Rating: 9V nominal (supports standard 9V batteries).
   • Current Rating: Typically supports up to 1A, depending on the cable gauge and quality.
   • Power Rating: Up to 9W (for devices drawing 1A at 9V).
3. Wire Gauge:
   • Typical Wire Gauge: 22 AWG or 24 AWG, multi-stranded for flexibility.
   • Wire Length: 15 to 30 cm (6 to 12 inches) is common, though custom lengths are available.
4. Connector Material:
   • Battery Connector Material: Plastic base with metal terminals (nickel or copper alloy).
   • DC Jack Material: Plastic or rubberized housing with metal pin (nickel-plated brass or copper).
5. Cable Type:
   • Insulation: PVC or rubber insulation.
   • Temperature Rating: Usually rated for -20°C to 80°C.
6. Polarity:
   • Standard Polarity: Red wire for positive (+) and black wire for negative (-). The center pin of the DC jack is usually positive, while the outer sleeve is negative.
7. Mechanical Features:
   • Snap Fit: The 9V battery clip is designed to securely snap onto the terminals of a 9V battery.
   • DC Jack Compatibility: Typically compatible with standard 5.5mm x 2.1mm barrel connectors, used in many consumer electronics.
8. Durability:
   • Connector Life: Rated for hundreds to thousands of mating cycles (battery connection and disconnection).
   • Cable Durability: Resistant to flexing, vibration, and wear in typical electronic environments.
9. Applications:
   • Use Cases: Powering small electronics projects, breadboard prototyping, DIY kits, and powering devices that accept DC input (e.g., small motors, lights, sensors).
