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.
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.

Blower / Fan Type
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)
Point / Spot / Gun Type
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.
