VACUUM SWITCH 21 SERIES

Vacuum Switch 21 series

Two-setting point switch, or one setting point switch output and one analog signal output type is avaialble.

  • To improve visibility, an LED display is adopted for the vacuum switch
  • LED displays indicates set-up pressure and working pressure
  • Two types of vacuum switch selection: Two switch output type, and one switch output and an analog output. A connector wiring realize easy layout
  • Three pipe connection methods are available: Push-in Fitting, M5 metric female thread, and direct mount.
  • Output detection accuracy is enhanced by the use of semiconductor switch
