Reduction adjustment man-hours
Feedback sensor
Detects the polarity of a discharged object
and measures the charged voltage.
 Rapid elimination of static electricity by using a feedback sensor
•
The speed of static electricity removal has been increased by reading the workpiece’s
electrostatic potential with the feedback sensor and then continuously emitting ions of
a reverse polarity.

Goes into pulse DC operation when
the ion balance is within ±30 V.

Operation mode after static electricity removal (ion balance: within ±30 V) can be selected.
Energy saving mode: Stops generating ions after static electricity removal to reduce power
consumption. Air consumption can also be reduced by switching a pneumatic valve with the
static electricity removal completion signal.
Note) The pneumatic valve must separately be procured.
Continuous static electricity removal mode: After static electricity removal, the ionizer changes to
pulse DC operation and continues to remove static electricity to make it approach 0 V even if
the ion balance is below 30 V.
