Installation Guide
- Mount the bar at 50 to 2000 mm from the target.
- Use Rc 1/8 air connection. Set pressure to 0.2 MPa typical.
- Connect 24 to 36 VDC power. Observe polarity.
- Wire NPN open collector outputs for warnings and alarms.
- Use the static elimination stop input for remote control.
- Keep the unit away from conductive dust and moisture.
- Verify ion balance after installation with a charge plate monitor.
Commissioning and Maintenance Convenience
This Keyence SJ-E084H offers remote control communication. You can stop static elimination via NPN or contact input. Alarm and condition warnings simplify diagnostics. The tungsten electrodes resist wear. Clean the bar with soft cloth and approved solvent. Check air pressure and ion balance regularly. The shockless resistive coupling reduces maintenance risk. The unit has no built-in ports, so use external controllers for advanced monitoring. The 1.10 kg body mounts easily on standard brackets.
Compatibility Notes
This ionizer works with common 24 to 36 VDC industrial power supplies. It accepts NPN open collector signals. It also accepts contact point inputs. The Rc 1/8 air port fits standard pneumatic fittings. It does not include built-in communication ports. For network integration, use external I/O modules. The SJ-E series shares accessories with other Keyence bar ionizers. Always confirm connector pinouts before wiring.
