Thanks to the extremely low power input, this fan is highly suitable for battery-operated devices. It is permanently protected electrically against reverse polarity, blocking 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 stiff plastic housing of PBT, HG-ball bearings, polyester-based PCB and absolute reliability.

The pulse is like a rectangular wave, the frequency correlates to 3x rotor speed. The amplitude appears periodically. At blocked rotor the output signal could be L (0,4V) or H (Vcc). 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 fans MFB25B… have tinned lead wire ends (without connector). Do not touch the rotor!
