SMC PFMB7 2-Color Digital Flow Switch (500 to 2000 L/min)

SMC PFMB7 series compact 2-color digital flow switch for dry air and N2 in large-flow ranges of 500, 1000 and 2000 L/min, with Rc1/2 or Rc3/4 body ports.

Key features

Range ability 100:1, minimum setting unit 1 L/min; about 66% lighter than the conventional PF2A
Rated flow ranges 5-500, 10-1000 and 20-2000 L/min
Outputs: dual NPN or PNP switch, or NPN switch + analog 1-5 V (for PFG300) or 4-20 mA (for PFG310)
Suffix options: lead wire with connector 2 m (standard), with rubber cover (W) or none (N); bracket (R); calibration certificate (A)
NPT/G threads and PNP + analog / external input outputs (E to H) available on order
Small-flow PFMB7201 is discontinued (replaced by PF2M721)
