SJ-E084L Keyence Bar Ionizer for Narrow Web Static Control
The SJ-E084L belongs to the Keyence SJ-E series of bar-type static eliminators. This small flow model uses corona discharge with a shockless resistive coupling design. The pulse AC method applies ±8000 V to generate dense ions. Hi-Power I.C.C. control holds ion balance at ±30 V under 0.2 MPa air pressure. With 13 tungsten electrodes and a 920 mm effective length, it fits narrow webs, small rolls, and compact machine frames. Total length is 800 mm, so it mounts inside tight production spaces. Engineers often pick the SJ-E084L for lines where a full-width bar will not fit.

Oiltech Controls Review
- The SJ-E084L targets narrow static zones, not full web widths.
- 13 electrodes give even ion coverage across 920 mm.
- Hi-Power I.C.C. reduces drift after long run hours.
- Small flow air port pushes ions into recessed areas.
- NPN outputs link straight to common PLC cards.
- Remote control communication supports line integration.
Oiltech Controls Insight
- Buy the SJ-E084L when bar length must stay under 1 m.
- Check air pressure first. 0.2 MPa gives rated balance.
- Keep install distance within 50 to 2000 mm.
- Use dry, clean air to protect tungsten electrodes.
- Pair with a stop input for safe maintenance.
- Order spare bars for lines with no downtime window.
Suitable Equipment
- Labeling heads and narrow web presses.
- Small film wrapping machines.
- Compact pouch and sachet lines.
- PCB depaneling and handling units.
- Tube, cap, and small part feeders.
- Tabletop printing and coating rigs.

Professional FAQ
Q: How do I know the SJ-E084L fits my line?
A: Measure your static zone first. This bar covers 920 mm with 13 electrodes. If your web is wider, step up to a longer SJ-E model.
Q: What air setup works best in real production?
A: Years of field use point to 0.2 MPa. Higher pressure wastes air and can disturb light webs. Always use dry, oil-free air.
Q: How often should I clean the electrodes?
A: Check them every few weeks in dusty plants. Clean with a soft brush and power off first. Dirty probes cause balance drift.
Q: Can I run it without the air supply?
A: Yes, but ion reach drops. The small flow port helps push ions into gaps. Use air when targets sit far from the bar.
Q: How do I choose between SJ-E084L and SJ-E180L?
A: Pick the SJ-E084L for narrow zones under 1 m. Choose the SJ-E180L for wide webs near 1880 mm. Match bar length to your static area.
