Keyence SJ-E204H Bar-Type Static Eliminator (Ionizer) – High-End Model
Keyence SJ-E204H is a high-end bar-type static eliminator from the SJ-E series. It uses corona discharge with a shockless resistive coupling structure. The pulse AC method applies ±8000 V. Hi-Power I.C.C. controls ion balance. This model suits long-range static removal in industrial automation.
Effective length reaches 2100 mm at 50 mm distance. Total length is 2000 mm. It has 65 electrodes. Installation distance ranges from 50 to 2000 mm. Ion balance stays within ±30 V at 300 mm or more with 0.2 MPa air. The unit operates on 24 to 36 VDC. Current draw is 700 mA at 24 V and 500 mA at 36 V. It weighs 2.15 kg.
This ionizer includes remote control communication. It offers NPN open collector outputs for ion level warning, condition warning, and alarm. A static elimination stop input is available. Air connection uses Rc 1/8 port. Recommended air pressure is 0.2 MPa. Operating temperature is 0 to +40 °C. Humidity range is 35 to 85 % RH without condensation. The electrode probe uses tungsten. Body materials include ABS, PBT, PP, LCP, PPS, SPS, and SUS.

Installation Guide
- Mount the bar at 50 to 2000 mm from the target.
- Use Rc 1/8 air port for clean dry air.
- Set air pressure between 0.1 and 0.5 MPa. Recommended value is 0.2 MPa.
- Connect 24 to 36 VDC power. Observe polarity.
- Keep wiring away from high-voltage lines to reduce noise.
- Use NPN open collector for stop input and alarm output.
Debugging and Maintenance Convenience
- Hi-Power I.C.C. keeps ion balance stable. This reduces manual adjustment.
- Remote control communication allows monitoring from a host system.
- NPN outputs give early warning for ion level and condition.
- Tungsten electrodes resist wear. Clean them with soft brush and dry air.
- Shockless resistive coupling improves safety during maintenance.
