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.

Features

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.

SJ-H series - Sheath-Sensing Ioniser

Sheath-Sensing Ioniser SJ-H series

Eliminate static electricity on a target area of up to 3000 mm at an installation distance of 300 to 1500 mm. The SJ-H Series provides high-speed static electricity elimination and is capable of eliminating static throughout the entire installation area.

Features

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.

SJ-LF series - Compact Fan Static Eliminator

Compact Fan Static Eliminator SJ-LF series

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.

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.

SJ-F2000/5000 series - High-speed, High-precision, Wide-area Static Elimination Blower

High-speed, High-precision, Wide-area Static Elimination Blower SJ-F2000/5000 series

Eliminate static electricity on a target area of 1000 mm at an installation distance of 200 to 1000 mm. With no need for an air supply, the SJ-F is suitable for desktop use.

Features

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.

Low Maintenance

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.

SJ-F300 series - High-Speed/Wide Area Static Eliminator

High-Speed/Wide Area Static Eliminator SJ-F300 series

Eliminate static electricity for a target area of up to 400 mm at an installation distance of 200 to 1000 mm. Without the need for an air supply, the SJ-F300 is suitable for desktop use.

Features

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)

SJ-F100 series - Standard Static Elimination Blower

Standard Static Elimination Blower SJ-F100 series

Eliminate static electricity for a target area of up to 300 mm at an installation distance of 200 to 500 mm. Without the need for an air supply, the SJ-F100 is suitable for desktop use.
