SMC PF3A7H Digital Flow Switch (Large Flow, 3-Color Display)

SMC PF3A7H Digital Flow Switch (Large Flow, 3-Color Display)

SMC PF3A7H series large-flow 3-color display digital flow switch for air and gases, in direct piping (up to 12000 L/min) and AC-D modular (up to 8000 L/min) types, with switch/analog or IO-Link output.

Key features

  • Direct piping type 30-3000, 60-6000 and 120-12000 L/min; modular type 5-500 to 80-8000 L/min for AC20-D to AC60-D
  • Range ability 100:1; 2-screen 3-color display of instantaneous and accumulated flow
  • Switch output NPN/PNP with analog voltage or current output or external input (CS/DS/ES/FS)
  • IO-Link versions (-L): L switch only, L3 with analog voltage, L4 with analog current
  • Used for air, nitrogen, argon and CO2; accumulated pulse output for remote monitoring
  • Thread Rc standard (NPT, G on order); lead wire options (N, Q), SI unit fixed (M) and flow direction (R) as suffixes
