Static electricity can disrupt high-speed manufacturing processes and damage sensitive components. The SJ-E204H addresses this challenge as a premium bar-type static eliminator from the Keyence SJ-E series. Specifically, this model combines a 2000 mm total length with 65 tungsten electrode probes. Therefore, it covers very wide webs, films, and conveyor widths effectively. With a 2100 mm effective range, the SJ-E204H suits large-format lines that need uniform ion coverage.
The SJ-E204H relies on a corona discharge method with a shockless resistive coupling structure. Moreover, it applies a pulse AC voltage of ±8000 V. This design generates abundant ions while maintaining safety. The Hi-Power I.C.C. (Intelligent Current Control) method continuously monitors and adjusts ion balance. Consequently, the unit achieves a balance of ±30 V under standard measurement conditions.
Key electrical ratings include a supply voltage of 24 to 36 VDC ±10%. Current consumption is 700 mA at 24 V or 500 mA at 36 V. The control output uses an NPN open collector rated for 100 mA maximum. Additionally, remote control communication is available for monitoring and adjustment. Built-in ports are not included, so external control relies on the remote communication protocol.
The effective static elimination length reaches 2100 mm when installed at a distance of 50 mm. Furthermore, the installation distance range spans 50 to 2000 mm, providing flexibility for different line layouts. The air connection port is Rc 1/8, and the recommended supply pressure is 0.2 MPa. Air supply may range from 0.1 to 0.5 MPa.
Operators can use this ionizer in ambient temperatures from 0 to +40°C. Relative humidity must stay between 35 and 85% RH without condensation. The electrode probes use tungsten for durability, while the main body consists of ABS, PBT, PP, LCP, PPS, SPS, and SUS materials. Finally, the unit weighs approximately 2.15 kg. The overvoltage category is I, and the pollution degree is 2.
First, mount the SJ-E204H securely using the appropriate brackets at the desired distance from the target. Next, connect the 24–36 VDC power supply and the air line to the Rc 1/8 port. After that, wire the control input for static elimination stop if needed. Finally, verify the ion balance and alarm outputs through the remote control communication interface.
