The **MA66TBX-R** is a specific electronic component typically categorized under **thermal management** or **electromechanical** parts. Specifically, it belongs to the series of AC Axial Fans produced by **Mechatronics**. Below is a detailed breakdown of its technical specifications and features. --- ### 1. Technical Specifications Table | Feature | Specification | | :--- | :--- | | **Manufacturer** | Mechatronics | | **Type** | AC Axial Fan | | **Frame Size** | 60mm x 60mm x 30mm | | **Voltage** | 115 VAC | | **Current / Power** | ~0.06A / 4.0 Watts | | **Speed** | ~3,100 RPM | | **Airflow** | ~11.0 CFM (Cubic Feet per Minute) | | **Bearing Type** | Ball Bearing | | **Termination** | Lead Wires (2-wire) | | **Noise Level** | ~28 dBA | --- ### 2. Part Number Breakdown The alphanumeric code provides specific details about the fan's construction: * **MA66**: Represents the frame size and series (60mm x 60mm x 30mm). * **T**: Indicates **Terminal** or **Terminal Connection** (though "T" often refers to the series housing type). * **B**: Stands for **Ball Bearing**. Ball bearings are superior for longevity and allow the fan to be mounted in any orientation (horizontal, vertical, or angled). * **X**: Usually denotes a specific **Speed/Performance** grade (Extra high or custom speed). * **-R**: Indicates **RoHS Compliant**, meaning the part is manufactured without hazardous substances like lead or mercury. --- ### 3. Key Electronic Features #### Bearing System The use of **Dual Ball Bearings** in this model provides a significantly longer life expectancy (often 50,000 to 70,000 hours) compared to sleeve bearing fans. It also handles higher heat environments more effectively. #### Motor Protection These fans typically include **Impedance Protection**. If the fan blades are obstructed (locked rotor), the internal impedance of the motor windings limits the current flow to prevent the motor from overheating or catching fire. #### Construction Materials * **Frame:** Die-cast aluminum (provides structural rigidity and heat dissipation). * **Impeller:** UL94V-0 reinforced plastic (flame retardant). --- ### 4. Typical Applications The MA66TBX-R is designed for industrial and commercial equipment where space is limited but reliable cooling is required: * Power supplies and transformers. * Small server rack enclosures. * Medical diagnostic equipment. * Industrial control panels.
