  • *Note 1) Options B, G and H are not assembled and are supplied loose at the time of shipment.
  • *Note 2) Set nuts are included with the bracket.
  • *Note 3) When choosing with H (panel mount), the installation space for lead wires will not be secured. In this case, select "wiring top entry" for the electrical entry. (Select "wiring bottom entry" when the semi-standard Y is chosen simultaneously.)
  • *Note 4) The pressure regulator spring is the only difference from the standard specification. Does not restrict setting to a pressure of 0.2 MPa / 0.6 MPa or higher. Moreover, if a pressure gauge is attached, a 0.2‑MPa-use pressure gauge for 0.2‑MPa settings will be fitted or a 0.7‑MPa‑use pressure gauge for 0.6 MPa settings. For all times when a digital pressure switch is attached, the pressure display is fixed to 1.0 MPa.
  • *Note 5) Thread type: NPT is applicable. Under new Japanese measurement laws, this product is only available for sale outside of Japan (SI units are used in Japan). The digital pressure switch, which has the unit selection function, has a default setting of psi.
  • *Note 6) Options: E1, E2, E3, E4. Under new Japanese measurement laws, this product is only available for sale outside of Japan (SI units are used in Japan).
  • *Note 7) ○ is for thread type NPT only.
  • *Note 8) △: Combination available for options E1, E2, E3, E4.
