Performance and Environmental Resistance

• The SJ-E156L keeps ion balance within ±30 V at the recommended air pressure.
• The Hi-Power I.C.C. method adjusts ion output to hold balance across the working range.
• Tungsten electrode probes resist wear and support long, stable service life.
• The mixed housing materials deliver mechanical strength and chemical resistance.
• The unit works from 0 to +40 °C and tolerates 35 to 85 % RH without condensation.
• Overvoltage category I and pollution degree 2 fit controlled factory environments.
• NPN open collector outputs report ion level warnings, condition warnings and alarms.

Installation Guide

• Mount the bar between 50 and 2000 mm from the surface you want to neutralize.
• Align the 1640 mm effective range with the charged area at 50 mm distance.
• Connect the air line to the Rc 1/8 port and set pressure from 0.1 to 0.5 MPa.
• Use 0.2 MPa recommended pressure to reach the rated ±30 V ion balance.
• Wire the 24 to 36 VDC supply and keep current draw within 700 mA at 24 V.
• Connect the static elimination stop input with an NPN open collector or contact point.
• Route alarm and warning outputs to a controller rated for 40 VDC or less.
• Check airflow and ion balance after mounting before starting full production.
