### Product Overview: DBCUSB2AB1M The **DBCUSB2AB1M** is a high-performance USB 2.0 cable commonly used in industrial, commercial, and professional audio/visual environments. It is specifically a **USB Type-A to Type-B** cable, typically measuring **1 meter** in length. --- ### Technical Specifications | Feature | Specification | | :--- | :--- | | **Connector A** | USB 2.0 Type-A (Male) | | **Connector B** | USB 2.0 Type-B (Male) | | **Length** | 1.0 Meter (approx. 3.3 ft) | | **Data Transfer Rate** | Up to 480 Mbps | | **Jacket Material** | High-quality PVC or TPE (Environmental) | | **Shielding** | Dual-layer (Foil + Braid) for EMI/RFI protection | | **Conductor Material** | Oxygen-Free Copper (OFC) | --- ### Electronic and Mechanical Components #### 1. Internal Wiring (Conductors) The cable consists of four main wires, typically color-coded to meet USB standards: * **VCC (Red):** Carries +5V DC power. * **GND (Black):** Ground wire for the circuit. * **Data+ (Green):** Differential positive data signal. * **Data- (White):** Differential negative data signal. #### 2. Signal Integrity Features * **Twisted Pair Construction:** The data lines (D+ and D-) are twisted together to minimize **crosstalk** and electromagnetic interference (EMI). * **Shielding:** To prevent signal degradation in noisy environments (near power supplies or motors), the cable uses aluminum mylar foil and a tinned copper braid. #### 3. Connectors * **Plating:** The connectors are often nickel or gold-plated to prevent oxidation and ensure a low-resistance connection. * **Strain Relief:** The molded boots at the ends prevent the internal solder joints from breaking when the cable is bent. --- ### Common Applications The Type-A to Type-B configuration is the standard for connecting a computer (Host) to various peripheral devices: * **Office Equipment:** Printers and scanners. * **Audio Gear:** USB DACs, MIDI controllers, and audio interfaces. * **Industrial:** PLCs (Programmable Logic Controllers) and CNC machine interfaces. * **External Storage:** Older external hard drive enclosures. --- ### Wiring Diagram Representation ```text Host (Type-A) Peripheral (Type-B) [ Pin 1 ] ---------- (+5V) ----------- [ Pin 1 ] [ Pin 2 ] ---------- (D-) ----------- [ Pin 2 ] [ Pin 3 ] ---------- (D+) ----------- [ Pin 3 ] [ Pin 4 ] ---------- (GND) ----------- [ Pin 4 ] Shell ------- (Shield) ---------- Shell ```
