■ Features Water and Dust Resistance Its IP68-rated* water and dust protection ensures stable fan operation even in harsh environments. High Airflow and High Static Pressure This fan delivers a maximum airflow of 3.83 m3/min and a maximum static pressure of 390 Pa. High Energy Efficiency and Low Noise The PWM control function enables the external control of fan speed, contributing to lowering noise and improving energy efficiency of devices. * The degree of protection (IP code) is defined by IEC 60529 (International Electrotechnical Commission). IP68: • Completely protected against dust • Protected against submersion in water ®150x35mm Specifications When the optional inlet nozzle (109-1081H) is mounted. 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%. Max input is 22 W at rated voltage. Motor case: Aluminum (Black coating), Impeller: Plastic (Flammability: UL 94V-0) Refer to specifications (L10 life: 90% survival rate for continuous operation in indoor free air at 60°C, rated voltage) Expected life at 40°C is for reference only. Current blocking function and reverse polarity protection 50/60 Hz, 500 VAC, for 1 minute (between lead wire conductors and motor case) At 1 m away from the air inlet Refer to specifications (Non-condensing) -30 to +70°C (Non-condensing) ® Red © Black [Sensor] Yellow [Control] Brown Approx. 3

■ 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) = 2 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 10 kΩ Control PWM input...
