Sensor Failure Analysis

Gideon Analytical Laboratories received two Sunon Maglev MC35101V2-000U-G99 12V fans which did not operate. Along with the nonoperational fans, two functional fans were also sent to us for comparison. The Sunon Maglev MC35101V2-000U-G99 12V fan is an axial DC fan, with a speed of 7500 RPM and airflow of 6.5 CFM. An axial fan is a type of fan that causes gas to flow through it in an axial direction, parallel to the shaft about which the blades rotate. The flow is axial at entry and exit. The fan is designed to produce a pressure difference, and hence force, to cause a flow through the fan. Our goal was to determine why the Sunon Maglev MC35101V2-000U-G99 12V fans were failing.

Gideon Analytical Laboratories received two image sensors with high impedance on the connector between pins 4 and 5, measuring 10 KHz. An image sensor or imaging sensor is a sensor that detects and conveys the information that constitutes an image. It does so by converting the variable attenuation of light waves (as they pass through or reflect off objects) into signals, small bursts of current that convey the information. The waves can be light or other electromagnetic radiation. Image sensors are used in electronic imaging devices of both analog and digital types, which include digital cameras, camera modules, medical imaging equipment, night vision equipment such as thermal imaging devices, radar, sonar, and others. kHz stands for kilohertz (10³ Hz). Hertz is the unit of frequency in the International System of Units (SI) and is defined as one cycle per second.It is named for Heinrich Rudolf Hertz, the first person to provide conclusive proof of the existence of electromagnetic waves. The goal was to analyze these sensors and identify the cause of increasing resistance.
