High Static Pressure and High Airflow This blower delivers a maximum static pressure of 540 Pa and a maximum airflow of 1.09 m3/min.* Blowers can send out straight airflow with high static pressure, making them suitable for localized and spot cooling applications. Water and Dust Resistance Its IP68-rated** water and dust protection ensures stable fan operation even in harsh environments. High Energy Efficiency and Low Noise The PWM control function enables the control of fan speed, contributing to lowering noise and improving energy efficiency of devices. * These values are for models 9W1BM12P2H001 and 9W1BM24P2H001 ** The degree of protection (IP code) is defined by IEC 60529 (International Electrotechnical Commission). IP68: • Completely protected against dust • Protected against submersion in water 97x33■ Specifications Models with the following sensor specifications are also available as options: Without sensor Lock sensor The models listed below have pulse sensors with PWM control function. * PWM frequency: 25 kHz. Fan does not rotate when PWM duty cycle is 0%.

97× 33 mm ■ PWM Input Signal Example Input signal waveform VIH = 4.75 to 5.25 V　VIL = 0 to 0.4 V PWM duty cycle (%) = T ×100 PWM frequency 25 (kHz) = T Current source (Isource) = 1 mA max. (when control voltage is 0 V) Current sink (Isink) = 1 mA max. (when control voltage is 5.25 V) Control terminal voltage = 5.25 V max. (when control terminal is open) When the control terminal is open, fan speed is the same as when PWM duty cycle is 100%. Either TTL input, open collector or open drain can be used for PWM control input signal. ■ Example of Connection Schematic ＋ ○ Input voltage ■ Specifications...
