Keyence SJ-E084L Bar-Type Static Eliminator
Product Introduction
The SJ-E084L belongs to the Keyence SJ-E series of energy-saving, high-speed sensing ionizers. This low-flow model combines a shockless resistive coupling structure with a pulse AC method operating at ±8000 V. Furthermore, the Hi-Power I.C.C. ion balance control system maintains stable performance under varying environmental conditions.
Specifically, the unit features 13 tungsten electrode probes distributed along an 800 mm total body length. Meanwhile, the effective static elimination range reaches 920 mm when installed at a distance of 50 mm. The Keyence SJ-E084L therefore suits production lines that require wide-area coverage without high compressed air consumption.
Technical Specifications
The SJ-E084L operates on a 24 to 36 VDC ±10% supply. Current draw is 700 mA at 24 V, dropping to 500 mA at 36 V. Ion balance is rated at ±30 V when measured at an installation distance of 300 mm or more with 0.2 MPa air pressure. Additionally, the recommended air supply pressure is 0.2 MPa, though the unit accepts a range from 0.1 to 0.5 MPa.
Control inputs include a static elimination stop input compatible with NPN open collector or dry contact signals. Outputs provide ion level warning, condition warning, and alarm signals through NPN open collector circuits rated at 100 mA maximum (40 VDC or less). The air connection port uses an Rc 1/8 thread. Communication is handled through remote control communication.
Mechanical and Environmental Parameters
The SJ-E084L body is constructed from ABS, PBT, PP, LCP, PPS, SPS, and SUS materials. Electrode probes use tungsten for durability. The unit weighs 1,070 g. Operating temperature ranges from 0 to +40 °C, with relative humidity tolerated between 35 and 85% RH without condensation. The overvoltage category is I, and the pollution degree is 2.
Installation Guidelines
First, mount the Keyence SJ-E084L within a distance of 50 to 2,000 mm from the target surface. The optimal balance performance occurs at 300 mm or greater. Next, connect the air supply to the Rc 1/8 port and regulate pressure to the recommended 0.2 MPa.
Furthermore, wire the 24 to 36 VDC power supply according to the polarity markings. Connect control input and output signals to the appropriate NPN open collector or contact interfaces. Finally, verify that the installation environment remains within the specified temperature and humidity limits.
