The Static-Sensing Ionizer discharges ions across a wide area and eliminates static charges from all types of surfaces. The new I.R.G. (Insert Ring Ground) design dissipates static five times faster than conventional models, while the Dual I.C.C. (Ion Current Control) system senses static conditions in the environment and automatically adjusts the ion output.

World’s Fastest Static Elimination Bar

The SJ-H Series speeds up static elimination by integrating a ring-shaped GND plate into the body of the Ionizer. Conventional ionizing bars use external GND plates that divert ions away from their target, resulting in slower static dispersion rates.

Covers Wide ESD-Sensitive Areas

The built-in GND plate produces a ring-shaped electric field that provides double the static elimination area of conventional models, making the SJ-H series optimal for wide target areas.

Automatically Adapts Ion Flow to Regulate ESD Conditions

The SJ-H series adopts the dual I.C.C. system that automatically adjusts both the applied voltage and the pulse width. When a statically charged surface is detected, the Ionizer instantaneously increases the production of either the positive or negative ions to eliminate the static charge.
