High-speed static elimination with no air flow

I.R.G. structure for air flow-free high-speed static electricity elimination

In conventional models, the GND plate essential for ion generation is mounted externally. KEYENCE's SJ-H Series, however, is the first to adopt the I.R.G. (Insert Ring Ground) structure, which includes the plate inside the ioniser. By directing the generated ions to the target rather than the GND plate, loss is minimised and the number of ions applied to the target increases. This allows for high-speed static elimination five times faster than conventional models.

High Usability

The SJ-H Series includes a self-diagnosis function that monitors the ion generation level. With the bar LED and alarm outputs, the ioniser alerts you when maintenance is required.

3-way alarm output

The SJ Series provides the self-diagnosis function that monitors three types of abnormalities. If an abnormality is detected, the LED indicators identify the error condition and an external output is activated. Centralised control of ionisers is enabled by monitoring the external output.

Cleaning warning
Monitors reduction in ion generation level due to dirt or wear of the electrode probe.

Condition warning
Monitors a high charge level that cannot provide a sufficient static elimination effect.

Alarm warning
Monitors abnormal discharge or damage to the ioniser.
