Packing Quantity PCs 50 - 100 - 500 This SEPA high-tech miniature fan is suitable for industrial or automotive use and has a remarkable air flow performance despite its small dimensions. Due to a nearly linear air performance characteristic, the fan is applicable for different uses. It is permanently protected electrically against reverse polarity, block- ing and thermal overloading. Due to the low rotor weight and precision balancing, it is virtually vibration- free. It is also insensitive to shock. Further features of this fan are its extremely robust and torsionally rigid plastic housing of PBT (UL E54695), ball bearings with narrow tolerances, of special steel, polyester-based PCB (UL E44247) and absolute reliability due to 100% burn-in.

An alarm-board is available on request. The pulse is like a rectangular wave, the frequency correlates to 2 x rotor speed. At blocked rotor the output signal could be L ( 0.4V) or H (5V). IMPORTANT: The pulse output is not protected against short circuit and must not connect to GND or Vcc without pre-resistor. A pull-up-resistor is needed. Do not connect not used pulse output (insolate). The MFB40H05(A) has tinned lead wire ends (without connector).
