Datasheet

Note 1) When a product with the backflow function (ARP20K to 40K) is chosen, set the inlet pressure to 0.05 MPa or higher than the set pressure.
Note 2) For the type set to 0.2 MPa only, repeatability will be within ±3 kPa.
Note 3) Port thread is not provided for products with square embedded-type pressure gauges.
Note 4) Weight shown is for products without any options.

Note 1) Assembly includes a bracket and set nuts.
Note 2)  in part numbers for a round-type pressure gauge indicates a type of connection thread. No indication is necessary for R; however, indicate N for NPT. The G thread is
unavailable. If it is required, select the R thread type (—) instead. Please contact SMC regarding the connection thread NPT and the pressure gauge supply for psi unit
specifications.
Note 3) Includes one O-ring and 2 mounting screws. [ ]: Pressure gauge cover only.
Note 4) Lead wire with connector (2 m), adapter, lock pin, O-ring (1 pc.), and mounting screws (2 pcs.) are included. [ ]: Switch body only.
For how to order the digital pressure switch, refer to the following specific page for the digital pressure switch.
