The Keyence SJ-M031G is a high-performance micro static eliminator head designed to deliver efficient, precise, and reliable static removal in sensitive industrial environments. Leveraging advanced ionization technology, compact design, and integrated monitoring capabilities, this unit is an ideal solution for applications where electrostatic charges can disrupt processes, damage products, or compromise quality control.

At its core, the SJ-M031G employs a pulse AC ionization method with an applied voltage of ±5.5 kV, producing a rated output of ±6 kV. This ensures that a powerful and consistent ion stream is generated, capable of neutralizing static charges quickly and effectively. Such performance is essential in industries like electronics, precision assembly, and semiconductor manufacturing, where even minor static discharges can cause serious defects or failures.

A standout feature of the SJ-M031G is its Ion Current Control (I.C.C.) technology, which provides highly stable ion balance management. The system maintains ion balance within ±30 V, preventing overcompensation or uneven static removal. This ensures that sensitive components, such as microchips, lenses, and thin films, are protected from static-related damage while maintaining the highest levels of process integrity.

The unit is also equipped with integrated monitoring and alarm functions for enhanced reliability. It includes outputs for ion level alarms, condition alarms, and an NPN open collector alarm capable of handling up to 100 mA at 40 V or less. These features provide real-time feedback to operators and automated systems, allowing for proactive maintenance and immediate responses to potential malfunctions. The ability to halt static elimination through a dedicated input adds another layer of operational safety and control.

In terms of physical design, the SJ-M031G offers compact efficiency. With an effective length of 164 mm and total length of 220 mm, it is engineered for easy installation in constrained spaces without sacrificing performance. Weighing approximately 600 g, the head unit is light enough for flexible mounting while still robust enough for continuous use in industrial environments. Its air purge system, requiring a supplied pressure of 0.2 MPa or less, further enhances performance by preventing dust accumulation on ionizing needles, ensuring long-term stability.

Built for demanding environments, the SJ-M031G operates reliably within an ambient temperature range of 0 to +40 °C and relative humidity of 35 to 65% RH without condensation. This makes it highly adaptable to a wide variety of manufacturing conditions.

In summary, the Keyence SJ-M031G combines advanced pulse AC ionization, precision ion balance control, real-time monitoring, and a compact design to deliver powerful and reliable static elimination. Its robust performance, ease of integration, and protective alarm functions make it an essential tool for industries where electrostatic discharge control is critical for maintaining product quality, yield, and process efficiency.
