Keyence SJ-E156L Small Flow Bar Ionizer
The Keyence SJ-E156L is a small flow bar type static eliminator. It uses corona discharge with a shockless resistive coupling structure. The pulse AC method applies ±8000 V for strong ion output. The Hi-Power I.C.C. method holds ion balance at ±30 V. This model fits narrow spaces and long production lines. The 25 tungsten electrodes cover a wide area. The effective length reaches 1640 mm at 50 mm distance. Air pressure runs from 0.1 to 0.5 MPa. The recommended value is 0.2 MPa. Installation distance is 50 to 2000 mm. The total length is 1520 mm. Weight is only 1.70 kg.

Installation Guide
- Place the bar 50 to 2000 mm from the target surface.
- Use the full 1640 mm effective length at 50 mm distance.
- Connect clean air to the Rc 1/8 port.
- Set pressure between 0.1 and 0.5 MPa. Target 0.2 MPa.
- Feed the unit with 24 to 36 VDC ±10%.
- Keep control output below 40 VDC and 100 mA.
- Operate between 0 and +40 °C.
- Keep humidity under 85 % RH. Avoid condensation.
Setup and Maintenance Convenience
The SJ-E156L uses NPN open collector signals for simple wiring. The static elimination stop input accepts NPN open collector or dry contact. Ion level warning, condition warning, and alarm output speed up fault finding. The Hi-Power I.C.C. control cuts manual tuning time. The shockless resistive coupling design protects operators. Maintenance focuses on keeping the 25 tungsten electrodes clean. No built-in port means the unit stays compact. Remote control communication handles external commands.
Compatibility Notes
- Matches common 24 VDC and 36 VDC industrial power rails.
- Remote control communication links to external control systems.
- No expansion port. Plan I/O at the system level.
- Use clean, dry air with a filter regulator.
- NPN output suits many PLC and motion controller inputs.
- Not rated for washdown or humidity above 85 % RH.
Certifications and Compliance
