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 minimize air resistance. With the world's first wide-angle booster, the SJ-H Series achieves a 90-degree-wide static elimination angle by utilizing 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.

High Usability

The SJ-H Series includes a self-diagnosis function that monitors the ion generation level. With the bar LED and alarm outputs, the ioniser alerts you when maintenance is required.

  • SJ-LF series - Compact Fan Static Eliminator

    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.

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

    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.

  • SJ-M series - High-Performance Micro Static Eliminator

    Eliminate static electricity for a target area of 200 mm at an installation distance of up to 200 mm. The SJ-M Series boasts an ultra-compact ⌀10 mm static electricity elimination head suitable for installations within equipment or in narrow spaces.

  • SK series - Electrostatic Sensor

    The SK Series makes it easy to instantly check static electricity levels on products and areas throughout a production environment. Use the SK Series to also confirm whether static eliminators are effective and to check humidity and temperature levels.
