Ultra-High Speed, Sheath-Sensing Ioniser
Static elimination capacity is powerful not only with compressed
air but also when there is no downflow.
(※KEYENCE comparison as of December 2007 using a corona discharge type static elimination bar)
Maintenance work can be drastically reduced without sacrificing elimination speed or ion balance.
Effective for applications with limited space and for weight reduction of existing systems.
A small volume of air flow effectively reduces both running costs and particles adhering to the electrodes.
The SJ-H Series adopts the I.R.G. structure that incorporates the GND plate essential for ion generation into the ioniser body. This GND plate is externally mounted on conventional models.
The I.R.G. structure directs the flow of generated ions toward the target object, instead of toward the GND plate. This structure increases the quantity of ions applied to the target, providing static elimination speed five times faster than conventional models.
With the ring-shaped design of the built-in GND plate, the SJ-H Series can radiate a uniform electric field in a ring pattern. Since the ions spread along the electric field, a circular, wide static elimination area can be provided. This feature is effective for applications that require wide area static elimination.
The dual I.C.C. system is further advanced from the conventionally proven I.C.C. system found in other KEYENCE models. The SJ-H Series static eliminators adopt a dual I.C.C. system that can change the applied voltage in addition to the variable pulse width, thus providing more flexible control of ion generation level per unit time.
This system enables optimum static elimination relative to a change in the ambient environment (temperature, humidity, etc.) and the electrode probe condition.
