The SJ-E084A belongs to the Keyence SJ-E series of energy-saving high-speed sensing ionizers. This standard bar-type model utilizes a pulse AC corona discharge method with an applied voltage of ±8000 V. Furthermore, its Hi-Power I.C.C. (Ion Current Control) system maintains ion balance within ±30 V, ensuring precise static neutralization in industrial automation environments. The unit features 13 tungsten electrode probes and an effective static elimination length of 900 mm when positioned at a 50 mm distance. Additionally, the shockless resistive coupling structure enhances operational safety. This ionizer is suitable for manufacturing lines involving electronics, packaging, and film processing where static buildup causes material attraction or discharge damage.
The SJ-E084A operates on a 24 to 36 VDC power supply with a current consumption of 700 mA at 24 V or 500 mA at 36 V. Its ion generation relies on a corona discharge method combined with a pulse AC voltage application. Specifically, the Hi-Power I.C.C. method actively adjusts ion output to compensate for environmental changes and electrode wear. The ion balance is rated at ±30 V under standard measurement conditions (300 mm distance, 0.2 MPa air pressure). Meanwhile, the installation distance ranges from 50 to 2000 mm, offering flexibility for different production line layouts. The unit contains 13 electrode probes made of tungsten, a material chosen for durability and resistance to wear.
The total length of the bar is 800 mm, while the effective static elimination range reaches 900 mm at a 50 mm distance. The main body is constructed from a blend of engineering plastics including ABS, PBT, PP, LCP, PPS, and SPS, along with SUS stainless steel components. The product weighs approximately 1.07 kg. For air-assisted operation, the unit provides an Rc 1/8 air connection port. The recommended air supply pressure is 0.2 MPa, with an acceptable range of 0.1 to 0.5 MPa. Operationally, the SJ-E084A functions within an ambient temperature range of 0 to +40 °C and a relative humidity of 35 to 85% RH without condensation. The pollution degree is rated at 2, and the overvoltage category is I.
First, mount the bar unit securely using the appropriate brackets at the desired location along the production line. Next, connect the power supply wiring to a 24 to 36 VDC source, ensuring correct polarity. The control input supports an NPN open collector or a dry contact signal for the static elimination stop function. For air-purge models, connect the Rc 1/8 fitting to a clean, dry air supply and set the regulator to the recommended 0.2 MPa. Furthermore, maintain an installation distance between 50 mm and 2000 mm from the target material for optimal performance. Finally, verify the ion balance and alarm outputs through the NPN open collector terminals (maximum 100 mA, 40 VDC or less) after powering up.

Q1: What is the effective static elimination length of the SJ-E084A?
A1: The effective length is 900 mm when the installation distance is set to 50 mm. However, this range may vary with the distance and air pressure used.
Q2: Does this model include a built-in communication port?
A2: No, the standard SJ-E084A model does not include built-in serial or Ethernet ports. Remote control communication is supported via dedicated optional remote controllers.
Q3: What type of electrode material does the SJ-E084A use?
A3: The unit uses 13 tungsten electrode probes. Tungsten offers high durability and resistance to spark erosion during continuous corona discharge.
Q4: Can I use the SJ-E084A without an air supply?
A4: Yes, the ionizer can generate ions without air. Nevertheless, supplying clean air at the recommended 0.2 MPa improves ion delivery speed and helps keep the electrodes clean.
Q5: What is the recommended power supply for this ionizer?
A5: The SJ-E084A requires a 24 to 36 VDC power supply with a tolerance of ±10%. The current draw is 700 mA at 24 V or 500 mA at 36 V.
