Ultra High-Speed, Sensing Ionizers
Ultra High-Speed, Sensing Ionizers SJ-H series
SJ-H Series is a collection of advanced ultra-high-speed, charge sensing ionizers featuring low maintenance with the highest level of static elimination performance in all environments. While air is commonly used to improve static removal ability, compressed air may cause problems in certain industrial situations. The SJ-H Series achieves the highest level of static elimination in the industry without the use of air. Air-assisted static elimination is also available. Equipped with a function that controls air-flow and ion generation, the SJ-H has achieved top-class low-maintenance in the industry. The smallest-in-class body includes features that support any and all static elimination needs. SJ-H ionizers have a wide range of uses.
High-Speed Static Elimination without Air
I.R.G. design for optimal ion flow
In conventional models, the ground plate is externally mounted. KEYENCE's SJ-H Series is the first to use I.R.G. (Insert Ring Ground) technology in which the ground plate is housed internally. By directing the generated ions to the target rather than the ground plate, the total number of ions that reach the target increases. This allows for high-speed static elimination that is five times faster than conventional models.
The SJ-H Series includes a self-diagnosis function that monitors the ion generation level. With the bar LED and alarm outputs, the ionizer 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. Centralized control of ionizers is enabled by monitoring the external output.
Monitors reduction in ion generation level due to dirt or wear of the electrode probe.
Monitors a high charge level that cannot provide a sufficient static elimination effect.
Monitors abnormal discharge or damage to the ionizer.
