Keyence SJ-E036L Bar-Type Static Eliminator

Keyence SJ-E036L Bar-Type Static Eliminator

Product Introduction

The SJ-E036L belongs to the Keyence SJ-E series of bar-type static eliminators. Specifically, this unit is the small flow model, which reduces compressed air use while keeping strong static elimination. Corona discharge generates ions, and a pulse AC method applies ±8000 V to the electrode probes. Therefore, the bar neutralizes both positive and negative charge quickly. Meanwhile, the Hi-Power I.C.C. method continuously corrects ion balance. This ionizer suits film converting, packaging, printing, and electronics assembly lines where dust attraction causes defects.

Technical Specifications

The SJ-E036L uses a shockless resistive coupling structure for safe operation. Its pulse AC method applies ±8000 V, and ion balance stays within ±30 V when measured at 300 mm or more with 0.2 MPa air pressure. Installation distance ranges from 50 to 2000 mm, which gives layout flexibility. Additionally, five tungsten electrodes sit along a 350 mm total length, and the effective static elimination range at 50 mm reaches 440 mm. Supply voltage is 24 to 36 VDC ±10%. Current consumption is 700 mA at 24 V and 500 mA at 36 V. Outputs include NPN open collector signals for ion level warning, condition warning, and alarm. Moreover, a static elimination stop input accepts NPN open collector or contact point signals. The air port is Rc 1/8, and supply pressure runs 0.1 to 0.5 MPa with 0.2 MPa recommended.

Mechanical and Environmental Parameters

The unit weighs 0.67 kg, and the body uses ABS, PBT, PP, LCP, PPS, SPS, and SUS materials. Electrode probes are tungsten for wear resistance. Operating temperature ranges from 0 to +40 °C, and relative humidity must stay between 35 and 85 % RH without condensation. Overvoltage category is I, and pollution degree is 2. Furthermore, the shockless resistive coupling design limits current through the probes, so operators can work near the bar safely. The compact body fits tight machine frames where larger ionizers cannot mount.

Installation Guide

First, mount the bar parallel to the charged surface at a distance between 50 and 2000 mm. Next, connect the 24 to 36 VDC supply and confirm the polarity is correct. Then, wire the NPN open collector outputs to your controller for ion level warning, condition warning, and alarm. Connect the static elimination stop input if your line needs remote shutdown. After that, attach the air line to the Rc 1/8 port and set pressure near 0.2 MPa. Finally, power the unit and verify ion balance with a charged plate monitor before production starts.

FAQ

Q1: What is the effective static elimination range?
At a 50 mm installation distance, the SJ-E036L covers a 440 mm effective length. The total bar length is 350 mm. Adjust mounting height to match your web or part width.

Q2: Why does this model use less air than standard bars?
The small flow design cuts compressed air consumption while keeping ionization strong. Therefore, it lowers operating cost on lines with limited air supply. Recommended pressure is 0.2 MPa.

Q3: What does the Hi-Power I.C.C. method do?
Hi-Power I.C.C. continuously monitors and corrects ion balance. Consequently, the bar holds balance within ±30 V even as electrodes wear. This reduces drift-related defects over long runs.

Q4: Can I stop static elimination remotely?
Yes. The SJ-E036L accepts a static elimination stop input via NPN open collector or contact point. This supports interlocking with machine safety or maintenance sequences.

Q5: What is the shipping method?
We ship all orders via Fedex, UPS, or DHL. Tracking information is provided after dispatch. Furthermore, each bar is packed with rigid cushioning to protect the electrodes in transit.
