*1) When using with deionized water (pure water), select L (SUS or FKM) as the material type.
*2) Since the AC coil specifications are equipped with a rectifying element, there is no difference in power consumption due to start-up and excitation.
The wattage will be 3.5 W at 110/220 V AC.
*3) Vibration resistance: No malfunction when tested under 5 to 200 Hz 1 sweep, axial and perpendicular directions of the armature, energized and non-energized conditions.
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 armature in both energized and non-energized conditions (once for each condition).
*4) Since the electrical connection is exposed, it is not water resistant.
