Sheath-Sensing Ioniser SJ-H series

Removal of Static Electricity from Entire Rooms High-Speed Static Elimination without Air

SJ-H series - Sheath-Sensing Ioniser

Eliminate static electricity on a target area of up to 3000 mm at an installation distance of 300 to 1500 mm. The SJ-H Series provides high-speed static electricity elimination and is capable of eliminating static throughout the entire installation area.

Applications

  • Static elimination in the coating process of bumpers

  • Static elimination of films

  • Static elimination of slitters

  • Defect prevention of adhesive painting on cardboard

Features

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.
