High-Pressure Blow Spot Type Static Eliminator
SJ-M400 series
Air Blow Gun Attachment, High-Pressure Blow Spot Type Static Eliminator
Air Blow Gun Attachment Available
High-pressure air purge with an air pulsing function
The solenoid valve control function allows intermittent generation of powerful ion air at a maximum of 0.7 MPa. The dust or dirt which adheres to and is hard to remove from a surface can be effectively removed by applying pulsed, ionized airstream. Moreover, the air reduction results of intermittent air purge are about 50% of continuous air purge.

Air blow gun attachment
In response to strong demand, an air blow gun attachment is now available for handheld operation. You can use the SJ-M400 Series easily and quickly to prevent dust adhesion in production cells or other processes.
Multi-functional controllers show various conditions
Condition monitor
The LED indicator and alarm output notify you that the electrostatic charge of the target is too strong to obtain a sufficient static elimination effect.
Electrostatic charge monitor
The electrostatic charge monitor indicates the strength and polarity of the target at a glance. The static elimination effect easily and quickly.
Ion level monitor
The amount of ion generation is determined by self-diagnosis and the result is indicated not only with the LED bars but also with an alarm output which is issued when the quantity falls below a certain level. This allows monitoring of problems such as dirt accumulation on electrode probes.
High-speed static elimination using KEYENCE's original pulse AC method
The pulse AC method applies positive and negative high voltage
alternately
to each electrode probe to generate ions of both polarities. It
generates more ions than the normal AC method. Moreover, the
changeable oscillation frequency ensures effective operation under
all conditions, including the static elimination of fast-moving
targets or of an entire area.
Accurate ion balance with the I.C.C. method
The I.C.C. method is a process that ensures quick static elimination by supplying ions according to the electrostatic charge of the target, which is calculated by sensing the ion current generated from the potential difference between the target and electrode probe. This achieves both accurate ion balance while also providing quick and effective static elimination.
Automatic sensing & feedback with the I.C.C. process
Since appropriately balanced ions are supplied according to the electrostatic charge of the target, no labourious initial settings are required during introduction or maintenance, ensuring more effective static elimination.
The I.C.C. based static elimination efficiency duration has increased. (Typical data with SJ-F300)
Pursuit of safety and maintainability on the site
Low-voltage 24 V wiring
Low-voltage 24 V wiring eliminates the adverse effect of discharge on cabling and surrounding equipment, allowing the construction of a highly reliable system.
Static elimination stop input
The application of voltage to the electrodes can be stopped while the main power supply is still active. This feature ensures safety during work or maintenance.
Cleaning alarm
The self-diagnostic function outputs an alarm when it detects that cleaning is necessary due to dirt accumulated on the electrodes. The cassette type electrode allows easy maintenance.
Abnormal discharge detection circuit
When abnormal discharge is detected, the eliminator issues an alarm output and cuts off the highvoltage power supply simultaneously to prevent problems.
CE-compliant
The SJ-M400 Series is compliant to CE standards, further increasing the reliability and safety of the high level of static elimination.
