The potential amplitude can be reduced with
SMC’s original dual AC type sensor.
Static neutralization in consideration of damage to a device which is sensitive to electrostatic discharge (ESD) can be achieved.
The potential amplitude generated in the applicable workpiece is reduced even if the workpiece is mounted within close proximity of the ionizer.
Potential amplitude:

reduction compared to the existing model
(Compared to the IZS31 series at an installation height of 300 mm)
Simple operation: Can be controlled by
powering the ionizer ON
Implementation of our original dual AC type
+ ions and − ions are dis-
charged at the same time to
allow the + and − ions to
reach the workpiece evenly,
thereby reducing the potential
amplitude.
AC type
+ ion and − ion layers reach
the workpiece alternately,
which increases the potential
amplitude.

The operating mode after static neutralization (when electrostatic potential: within ±30 V) can be selected.
Energy saving mode
Stops generating ions after static neutralization to reduce power consumption
Continuous static neutralization mode
After static neutralization, the ionizer continues to neutralize
static electricity in AC mode while maintaining the electrostatic potential within
±
30 V.
