・Rated current, maximum air ow, maximum static pressure, and sound pressure level are the values given when duty cycle 100%.
・Storage temperature is -30˚C to +70˚C. For operating temperature range, see individual speci cation sheet.
・Switching with the PWM control may affect the sensor output. ・Speci cations may be changed without notice.

Technical Material
The PWM speed control function is a function that externally controls the rotation speed of the fan by changing the duty of the input pulse
signal between the control terminal and GND.
It regulates optimum air ow for ef cient cooling when necessary, and is effective for lowering power consumption and reducing equipment
noise level.
* Some models can not have PWM speed control function. Contact us for more information.

Source Current ( I source ) : 1mA Max. at control voltage 0V
Sink Current ( I sink ) : 1mA Max. at control voltage 5.25V
Control Terminal Voltage : 5.25V Max. ( When control terminal is opened )
When the control lead wire is open, speed is same as one at 100% PWM duty cycle.
This fan speed should be controlled by PWM input signal of either TTL input or open collector, drain
input.
