Notes:

1)	Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature of +23 ℃ +73.4 ℉.
2)	The response frequency is the value when the disc, given in the figure below, is rotated.
3)	In case the PM-24 series is used at an ambient temperature of +50 ℃ +122 ℉, or more, make sure to mount it on a metal body.
4)	Take care that the flexibility of the PM-□24-R cable is lost if the ambient temperature in –10 ℃ +14 ℉ or less.
5)	The cable of PM-□24-R is a flexible cable usable on a moving base. When the sensor is mounted on a moving base, fix the sensor cable joint so that stress is not applied to it. (Models other than the PM-□24-R cannot be used on a moving base.)
