TECHNICAL MATERIAL
Specifications for DC fan sensors
Pulse sensor outputs two pulse waves per revolution of fan, and it is good to detect fan speed. Pulse sensors can be incorporated in all
kinds of BLDC fans.
* Noise from inside the fan or from external devices may effect sensor output, please contact Sanyo Denki.
(Typical standard model: 109R1212H101).
