, or more, cable.
Weight Net weight: 10 g approx.
Notes: 1) Where measurement conditions have not been specied precisely, the conditions used were an ambient temperature of +23 °C +73.4 °F.
2) The response frequency is the value when the disc, given in the gure below, is rotated.
3) In case the ultra-small type PM-□24(-R) is used at an ambient temperature of +50 °C +122 °F, or more, make sure to mount it on a metal body.
4) Take care that the exibility of the PM-□24-R cable is lost if the ambient temperature in –10 °C +14 °F or less.
5) The cable of PM-□24-R is a exible cable usable on a moving base. When the sensor is mounted on a moving base, x 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.)
