SJ-E series - Energy-Saving High-Speed Sensing Ionizer

Energy-Saving High-Speed Sensing Ionizer SJ-E series

The Energy-Saving High-Speed Sensing Ionizer SJ-E Series saves energy while still providing high-speed static elimination. The supersonic air flow and structural optimization of electrode positions successfully reduce air consumption by 60% compared to conventional models. The result is static elimination with minimal running costs, a necessity amid rising electricity costs and the trend toward SDGs. Furthermore, the utilized supersonic structure reduces the adherence of foreign particles to static elimination probe tips, minimizing the need for maintenance even though a low volume of air is used.

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 ionizers, 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 - Air-Free High Speed Sensing Ionizer

Air-Free High Speed Sensing Ionizer 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 ionizer. 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.
