9AH0912M403 Sanyo Denki 12V 0.08A 92mm 9225 DC Axial Fan

Description

The Sanyo Denki 9AH0912M403 is a high-performance 12 V industrial axial fan with dimensions of 92 x 92 x 25 mm, purpose-built to deliver elite-level thermal cooling in high-resistance airflow paths. This unit features a heavy-duty brushless DC motor capable of sustaining a 0.96 W power input to drive its specialized 7-blade impeller at a consistent 2500 RPM. Engineered specifically for air displacement in standard-profile enclosures, it utilizes a 25 mm housing to provide balanced pressure and airflow for mission-critical hardware. The mechanical design relies on precision dual ball bearings and a fiberglass-reinforced PBT housing to ensure 40,000 hours of continuous operation at a 60 °C ambient temperature. Featuring a robust 3-wire electrical interface with a dedicated Tachometer (FG) output for real-time speed monitoring, this fan is a critical component for server racks, power supply cooling, and industrial automation where long-term reliability and precise system feedback are mandatory.
