Note 1) DC solenoid without a light/surge voltage suppressor
Note 2) AC or DC solenoid with an indicator light: It will cause delays around 20 to 30
msec in the OFF response time.

Note 1) Impact resistance:
No malfunction resulted in an impact test using a drop impact tester. The test was per-
formed one time each in the axial and right angle directions of the main valve and arma-
ture, for both energized and de-energized states. (Value in the initial stage)
Vibration resistance:
No malfunction resulted in 8.3 to 2000 Hz, a one-sweep test performed in the axial and
right angle directions of the main valve and armature for both energized and de-energ-
ized states. (Value in the initial stage)
Note 2) Vibration resistance is 50 m/s
2
when a light/surge voltage suppressor is attached.
Note 3) No inrush voltages are generated in the AC solenoid because a full-wave rectifier is used.
