*1: The minimum operating frequency is according to JIS B 8373 (once per 30 days).
*2: Based on JlS B 8375-1981, at 0.5 MPa with no surge voltage suppressor.
*3: Grommet value (sub-plate weight 0.05 kg).
*4: *1 and *2 assume controlled clean air.
*5: Based on JIS C 0920.
*6: Impact resistance: No malfunctions after testing using a drop-type impact tester under the following conditions: in the axial direction and at a right angle to the main valve and armature in both energized and non-energized states (once for each condition state). (Initial value)
Vibration resistance: No malfunctions occurred in a 1-sweep test between 45 and 2,000 Hz. The test was performed in both energized and non-energized states and in the axial direction and at right angles to the main valve and armature. (Initial value)
