SMC PF3A8H-L Digital Flow Switch with Pressure/Temp. Sensor

SMC PF3A8H-L Digital Flow Switch with Pressure/Temp. Sensor

SMC PF3A8H-L series modular IO-Link digital flow switch with built-in pressure and temperature sensors and 4-screen display, connecting to AC20-D to AC60-D combinations.

Key features

  • Measures flow, pressure (0 to 1.0 MPa) and temperature (0 to 50°C) in one modular unit
  • 4-screen display; IO-Link/switch output (OUT1) plus switch output (OUT2), NPN/PNP selectable
  • Rated flow ranges 5-500 to 80-8000 L/min for AC20-D to AC60-D modular F.R.L. combinations
  • Used for air, nitrogen, argon and CO2
  • Lead wire options (N, Q), SI unit fixed (M) and flow direction (R) as suffixes; spacers and piping adapters ordered separately
