Keyence SJ-E156L Bar-Type Static Eliminator
Product Introduction
The SJ-E156L serves wide production lines that need full-width static control with low air demand. This low-flow model pairs a shockless resistive coupling structure with a pulse AC method running at ±8000 V. Furthermore, the Hi-Power I.C.C. ion balance control system keeps output stable as ambient conditions shift.
Specifically, the bar carries 25 tungsten electrode probes along a 1520 mm total body length. Meanwhile, the effective static elimination range reaches 1640 mm when the bar sits 50 mm from the target. The Keyence SJ-E156L therefore suits wide film, coating, and converting lines that demand broad neutralization coverage.
Technical Specifications
The SJ-E156L runs on a 24 to 36 VDC ±10% supply. Current draw is 700 mA at 24 V and falls to 500 mA at 36 V. Ion balance is rated at ±30 V when measured at 300 mm or more with 0.2 MPa air pressure. Additionally, the recommended air supply pressure is 0.2 MPa, while the unit accepts 0.1 to 0.5 MPa.
Control inputs include a static elimination stop input that works with NPN open collector or dry contact signals. Outputs deliver 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, and communication runs through remote control communication.
Mechanical and Environmental Parameters
The SJ-E156L body uses ABS, PBT, PP, LCP, PPS, SPS, and SUS materials. Electrode probes are tungsten for long service life. The unit weighs 1,700 g. Operating temperature spans 0 to +40 °C, and relative humidity is tolerated from 35 to 85% RH without condensation. The overvoltage category is I, and the pollution degree is 2.
Installation Guidelines
First, mount the Keyence SJ-E156L between 50 and 2,000 mm from the target surface. Best 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 correct NPN open collector or contact interfaces. Finally, confirm that the installation environment stays within the specified temperature and humidity limits.
