This _**SEPA**_ ® high-tech miniature fan is suitable for industrial use and has a remarkable air flow performance despite its small dimensions. 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.

The pulse is like a rectangular wave, the frequency correlates to 2x rotor speed. The amplitude appears periodically. At blocked rotor the output signal could be L (0,4V) or H (Vcc). **==> picture [469 x 193] intentionally omitted <==** **----- Start of picture text -----**
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).
