Features

High-speed static elimination without air

I.R.G. design for optimal ion flow

In conventional models, the ground plate is externally mounted. KEYENCE's SJ-H Series is the first to use I.R.G. (Insert Ring Ground) technology in which the ground plate is housed internally. By directing the generated ions to the target rather than the ground plate, the total number of ions that reach the target increases. This allows for high-speed static elimination that is five times faster than conventional models.

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 ionizer alerts you when maintenance is required.

3-way alarm output

The SJ Series provides the self-diagnosis function that monitors three types of abnormalities. If an abnormality is detected, the LED indicators identify the error condition and an external output is activated. Centralized control of ionizers is enabled by monitoring the external output.

Cleaning warning
Monitors reduction in ion generation level due to dirt or wear of the electrode probe.

Condition warning
Monitors a high charge level that cannot provide a sufficient static elimination effect.

Alarm warning
Monitors abnormal discharge or damage to the ionizer.

  • SJ-LF series - Compact Fan Static Eliminator

    SJ-LF Series compact fan static eliminators are anti-static blowers that allow operators to “see” whether there is static and “verify” that static has been removed. The “visualizing light” and large indicator display the electrostatic level. This means that it is possible to instantly determine whether the static on the target object has been properly eliminated, making operations checks during startup easy. The compact body is one-fifth of the size of conventional small blowers, which gives the SJ-LF an array of different installation options. The main unit itself can generate airflow, so there is no need to supply air from a compressor. The SJ-LF Series is a lineup of static neutralizing blowers that embody solutions to on-site needs, alerting operators to errors and failures with alarms, including an ion level alarm.

  • SJ-F2000/5000 series - High-Speed, High-Precision, Wide-Area Static Elimination Blower

    SJ-F2000/5000 high-speed, high-accuracy wide static elimination blowers are wide sensing ionizers that neutralize static-induced problems by removing static from the environment, including products, human bodies, and peripheral parts. The fastest-in-class static elimination performance and high-precision ion balance, together with the wide-range airflow adjustment function, support various settings for a static-free environment. Because ions are supplied at the optimal balance that matches the electrostatic charge, no cumbersome initial settings are required during implementation or maintenance, delivering even more effective static electricity elimination. SJ-F2000/5000 Series static elimination blowers offer high performance and excellent usability at a higher level. With functions that suppress wear and dirt build-up in the elimination probe, the static control system employs a structure that allows easy maintenance, and a compact body that takes little space for installation.

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

    The high-performance SJ-M Series micro static eliminators are used as ultra-small embedded static eliminators. Spot nozzles and wide-area electrode probes are available depending on the required range of static elimination. Spot nozzles can focus on ionization and be built into a system designed to withstand high temperatures up to 80℃. The high-functionality controller indicates the static elimination status with an electrostatic monitor that shows the level of electrostatic charge of the target object, an ion level monitor that self-diagnoses and displays the ion level, and a condition monitor that displays and outputs an alarm when the static elimination effect is insufficient. In their small enclosures, the SJ-M Series micro static eliminators embody versatility that covers both spot and wide-area applications, a robustness that endures high temperatures, and best-in-its-class static elimination performance.

  • 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.
