Static Eliminators / Ionisers
Ionisers and static eliminators that automatically monitor and optimise static elimination of a target. Equipped with maintenance features that maintain high-performance for longer, the lineup includes a bar type, a blower type, and a spot type. This allows for elimination in various environments, from entire rooms to specific points.

The three technologies that support our ability to provide optimum static elimination with the lowest air volume in the world
By using the first supersonic structure ever developed in the history of ionisers, KEYENCE has increased the speed of ions past the speed of sound, which makes the fastest static elimination in the world possible with an extremely low air volume.
Optimum Static Elimination & Energy Saving
We have used de Laval nozzles, which are used in supersonic jet engine technology, in the electrode probes to realise our supersonic structure. The air speed exceeds the speed of sound, which enabled us to rapidly improve the speed at which ions attach to the target. In addition, the shape of the electrode probes, which makes use of fluid mechanics, pulls in the surrounding air to increase the air volume. These two technologies are what enable static elimination at high speeds and over a wide range with the lowest air volume in the world.
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.
Taking Advantage of a Dedicated Built-in Booster for Static Electricity Elimination over a Wider Range and at Ultra-high Speeds
Newly developed booster for ultra-high-speed static elimination over a wide angle
The new aero body was developed with thorough fluid analysis to minimise air resistance. With the world's first wide-angle booster, the SJ-H Series achieves a 90-degree-wide static elimination angle by utilising the Coanda effect with the air flowing from the booster. By attaching the straight air booster with extraordinary ion transport capabilities, an unparalleled static elimination speed is achieved. This function can ensure excellent static elimination capacities at ultra-long operating distances for highly charged objects.

Products Lineup : Blower / Fan Type
Small, easy-to-mount static eliminator that features visible feedback indicating whether a target has a static charge or not. The target area will light orange when static is present and green when absent. Easy installation and low-cost make this an ideal solution for troublesome areas.
Visualising Light: Static Electricity is Visible
Confirm if static was eliminated from any angle. Check operation without any additional sensors and easily reduce the problems caused by static electricity.
Smallest in Class: Fits in the Palm of Your Hand
The SJ-LF is small enough to be mounted anywhere, enabling it to be retrofit into existing equipment or installed in tight spaces where conventional static eliminators won't fit.
Highest Static Elimination Speed in Its Class
Through the combination of the well-proven pulse AC method and I.C.C., the SJ-F2000/F5000 Series has achieved the best ion generation per electrode in its class.
A high-power fan and a louver structure have been incorporated to provide a wide static elimination area with the fastest speed in its class.
KEYENCE's original I.C.C. has been incorporated to reduce the degradation of static elimination speed resulting from worn or dirty probes and to achieve three times longer operation with low maintenance compared to conventional models.
2× larger area compared to conventional models
High-power, wide-area fan achieves a static elimination area two times larger than conventional models.
The high-power, wide-area fan increases the air volume three times over that of conventional models. Moreover, the lossless structure minimises air resistance as much as possible. In spite of its small size, the SJ-F300 Series has a 2 times larger static elimination area compared to conventional models. It is especially effective for eliminating static electricity in cellular manufacturing assembly processes or from precision components.
2× faster speed compared to conventional models
High speed, straight louver achieves static elimination speeds two times faster than conventional models.
The newly developed high-speed straight louver has allowed the SJ-F300 Series to send air ions generated by corona discharge straight to distant areas without dispersing them. High-speed long-range static elimination is possible in a label packaging or filling processes. (Patent-pending)
Products Lineup : Spot / Nozzle type
Multi-Angle Static Electricity Elimination
Achieve static electricity elimination at any angle without having to change mounting positions. Never worry about not having enough space for retrofitting equipment or needing to remove static electricity at specific locations.
Easy Determination of Effectiveness!
Light-Based Static Electricity Visualisation
Determine the static charge of targets with colour. The ability to quickly verify whether static electricity has been removed properly at any angle makes it possible to easily check static electricity elimination effects at startup and during operation.
Ultra-small Static Elimination Head Has No Limitation on Installation Space
Since the SJ-M Series provides a direct static elimination structure that directs the ion generation point at the tip of the head, it allows for high-speed and high-precision static elimination where it is needed most.
Static Elimination over Areas at Distances of 1 m or More Using a ⌀12 mm Head
Remove static electricity from an area as large as 600 × 1500 mm using just a compact head. Eliminate static from more than 1 m away in under 1 second. Use branching to remove static electricity from inside devices.

Products Lineup : Gun type
Impressive Dust Removal Performance 3× More Powerful
The device’s Laval nozzle structure—which is also used in jet engine technology—pushes out air at supersonic speeds. Adding ions to this ultra-high-speed air helps not only remove foreign particles but also keep particles from re-adhering.
Ultra-robust All-in-One Design
The device’s ultra-rugged body is equipped with a rubber protector capable of withstanding strong impacts, preventing breakage even when the device is dropped from 2.0 m. The long service life and highly durable design ensure the device can be used with confidence even in frequently used sites.
