Use external pilot type in the following
cases:
• For vacuum or for low pressure 0.2 MPa or
less
• Please consult with SMC for use in a
vacuum hold application.
• When having P port downsized in diameter
• When using A port as the atmospheric
releasing port, e.g. air blower
• If manifold, external pilot piping can be
centralized in manifold base.

Note) Based on dynamic performance test, JIS B 8375-1981. (Coil temperature: 20
°
C, at rated voltage)
Pressure specifications
Note 1) It is in common between 110 VAC and 115 VAC, and between 220 VAC and 230 VAC.
Note 2) Allowable voltage fluctuation is –15% to +5% of the rated voltage for 115 VAC or 230 VAC.
Note 3) Since voltage drops due to the internal circuit in S, Z, T types (with power saving circuit), the
allowable voltage fluctuation should be within the following range.
24 VDC: –7% to +10%
12 VDC: –4% to +10%

• Refer to back page 8 for
changing the type of actuation.
Note) Impact resistance: No malfunction occurred when tested in both the axial and right angle directions
of main valve and armature (tested in both energized and de-energized states).
(Values at the initial period).
Vibration resistance: No malfunction occurred when tested in a one-sweep test between 45 and 2000
Hz, in both the axial and right angle directions of main valve and armature (tested
in both energized and de-energized states). (Values at the initial period).
