The **AFB0612VHC-R00** is a high-performance DC axial fan manufactured by **Delta Electronics**. It is commonly used in industrial computing, servers, and telecommunications equipment for localized cooling. --- ### 1. Key Technical Specifications | Parameter | Specification | Details | | :--- | :--- | :--- | | **Model Number** | AFB0612VHC-R00 | Part of the AFB series | | **Frame Size** | 60mm x 60mm x 15mm | Compact square footprint | | **Rated Voltage** | 12 VDC | Standard PC/Industrial voltage | | **Operating Voltage** | 7.0 to 13.8 VDC | Functional range | | **Rated Current** | 0.24A (Max 0.36A) | Power consumption approx. 2.88W | | **Speed** | 5,400 RPM | High-speed rotation | | **Airflow** | 28.18 CFM | 0.798 m³/min | | **Noise Level** | 38.0 dB-A | Notable acoustic signature | | **Bearing Type** | Ball Bearing | Dual ball bearing for longevity | --- ### 2. Electronic Signal & Wiring (R00 Suffix) The suffix **"-R00"** is critical as it defines the electronic output of the fan's internal circuitry. * **Sensor Type:** **Locked Rotor Sensor (High/Low)**. * **Function:** Unlike a "Tachometer" (which sends a pulse based on speed), the **R00** version provides a logic signal that indicates if the fan is spinning or stalled. * **Logic State:** Usually, the output stays "Low" when the fan is running and switches to "High" (or Open Collector) when the rotor is locked/stopped. * **Wiring Color Code:** 1. **Red:** Positive (+12V) 2. **Black:** Negative (GND) 3. **Blue (or White):** RD (Rotation Detector) Signal --- ### 3. Structural & Material Components * **Frame/Impeller:** Plastic (UL 94V-0) - This is a flame-retardant material required for industrial safety standards. * **Motor Type:** Brushless DC (BLDC) motor. It uses electronic commutation rather than carbon brushes to reduce wear and electromagnetic interference (EMI). * **Protection Features:** * **Polarity Protection:** Prevents damage if the +/- wires are reversed. * **Locked Rotor Protection:** The motor will attempt to restart automatically if it detects an obstruction. --- ### 4. Application Context Due to the **high RPM (5,400)** and **Ball Bearing** design, this fan is engineered for: * **High Static Pressure:** Pushing air through dense heat sinks or dust filters. * **Long Life:** Rated for approximately 70,000 hours at 40°C. * **Safety Monitoring:** The R00 signal allows a motherboard or PLC to trigger an alarm immediately if the fan fails.
