These SEPA® high-tech miniature fans are suitable for industrial or automotive use and have a remarkable air flow performance despite its small dimensions. Due to a nearly linear air performance characteristic, the fans are applicable for different uses. They are permanently protected electrically against reverse polarity, blocking and thermal overloading. Due to the low rotor weight and precision balancing,
they are virtually vibration-free. They are also insensitive to shock.
Further features of these fans are there 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.

3 Pulses / Rev. - 2 Pulses / Rev.
• ALARM SIGNAL (Optional)
The SEPA® MFB50xxxA include a pulse output, which allows monitoring the correct function of the fan.
An alarm-board is available on request.
MFB50A05A: The pulse is like a rectangular wave, the frequency correlates to 3 x rotor speed. At blocked
rotor the output signal could be L (≤1,0V) or H (4.0V). A pull-up-resistor is not needed (push-pull).
MFB50C12A: The pulse is like a rectangular wave, the frequency correlates to 2 x rotor speed. At
blocked rotor the output signal could be L (≤0.3V) or H (12V). A pull-up-resistor is needed.
IMPORTANT: The pulse output is not protected against short circuit and must not connect to GND or
Vcc without pre-resistor.
Do not connect not used pulse output (insolate).
Do not touch the rotor!
The MFB50xxx(A) have tinned lead wire ends (without connector).
