Note
1) This product is for dry air. Use in clean air, and be sure that drain and oil content does not flow into
the product.
Note 2) Use dry air to prevent condensation when operating at low temperatures.
Note 3) Manual override is available only for DIN terminal type.
Note 4) Vibration resistance: No malfunction occurred in a one-sweep test between 8.3 and 2000 Hz. Test
was performed at both energized and de-energized states to the axis and right
angle directions of the main valve and armature (value at the initial state).
Shock resistance: No malfunction resulted from the impact test using a drop impact tester. The
test was performed on the axis and right angle directions of the main valve and
armature for both energized and de-energized states (value at the initial state).
Note 5) DIN terminal type: Applicable to dusttight and low jetproof (IP65).

Note 1) JIS B 8375 (value of DC voltage specifications at 0.5 MPa supply pressure)
(Value of high response time is subject to change upon pressure, quality of air.)
Note 2) It cannot be used when energized continuously.
Note 3) If a restrictor (nozzle, etc.) is mounted on the outlet side piping, the pressure differential when
ON is smaller. Be sure that the pressure differential does not drop below 0.01 MPa.
