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.

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.
