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-25 series is used at an ambient temperature of +50 ℃ +122 ℉, or more, make sure to mount it on a metal body.
4) Note that the cable of PM-□25-R loses its flexibility when the ambient temperature decreases to about -10 ℃ +14 ℉.
5) The cable of PM-□25-R is a bending-resistant cable usable on a moving base. When the sensor is mounted on a moving base, secure the sensor cable joint at the unit in place so that stress is not applied to it.
6) When storing PM-□25-R, make sure that the cable does not come into contact with the sensing section or operation indicator.
7) If the cable is extended to 20 m 65.617 ft or longer, confirm that the supply voltage at the end of the cable attached to the sensor is 4.5 V or higher.
