Note 2) Since AC coil uses a rectifying circuit, there is no difference in power consumption between inrush and holding. Note 3) When using seal material PTFE at 15 cm3/min (under water pressure) or less. Note 4) Vibration resistance ・・・・ Conditions when tested with one sweep of 10 to 250 Hz in the axial direction and at a right angle to the armature, in both energized and deenergized states. No malfunction occurred when tested (value at the initial state). Impact resistance ・・・・ Conditions when tested with a drop tester in the axial direction and at a right angle to the armature, one time each in energized and deenergized states. No malfunction occurred when tested. (Value at the initial state).
