109P0912H4D01 Sanyo Denki 12V 0.21A 92mm DC Axial Fan

Description

The Sanyo Denki 109P0912H4D01 is a high-reliability industrial DC Axial Fan with dimensions of 92 x 92 x 25 mm. Driven by a precision Brushless DC Motor, this San Ace 92 series model is engineered as a robust thermal management solution operating on a nominal 12 VDC. It delivers a steady maximum airflow of 46.6 CFM (79.2 m³/h) at a rated speed of 2850 RPM. With a rated current of 0.21 A and a power input of 2.52 W, it is specifically designed for consistent performance in industrial controllers and medical diagnostics equipment. This specialized 3-wire version features a premium dual-ball bearing system and an optimized 7-blade impeller. Crucially, it is equipped with a Lock Sensor (D-Type) signal, which outputs a logical signal to indicate whether the fan is rotating or stopped. The 109P0912H4D01 provides mission-critical reliability with a life expectancy of 60,000 hours, making it an ideal choice for 12V systems requiring a standard 92 mm form factor with integrated rotation failure detection.

Application
The 109P0912H4D01 is primarily utilized as a thermal management component for industrial automation controllers, server rack sub-systems, and sensitive medical imaging equipment. Its 92 mm frame size is a standard for mid-sized electronics enclosures, providing a balance between high airflow (46.6 CFM) and low acoustic noise (34 dB(A)). The integrated Lock Sensor is the most critical feature for these applications; it allows the host system to immediately trigger a shutdown or alarm if the fan stops spinning due to an obstruction or bearing failure, thereby preventing catastrophic overheating of the internal CPU or power modules. This model’s dual-ball bearing construction ensures a long 60,000-hour service life, making it a reliable choice for 24/7 continuous operation in professional 12V DC environments.
