Keyence SJ-E156H Static Eliminator: High-End Bar Ionizer for Extra-Wide Static Control
Product Introduction
The Keyence SJ-E156H is a high-end bar-type static eliminator from the SJ-E series. This model uses a corona discharge method with a shockless resistive coupling structure. Specifically, it applies a pulse AC voltage of ±8000 V to produce positive and negative ions. The Hi-Power I.C.C. method then holds ion balance within ±30 V. As a result, the SJ-E156H removes static charge quickly from extra-wide targets. Furthermore, 49 tungsten electrodes and a 1620 mm effective length cover long webs and conveyors in a single pass.
Technical Specifications and Performance Features
The SJ-E156H operates on a 24 to 36 VDC ±10% supply. Current consumption reaches 700 mA at 24 V and 500 mA at 36 V. Besides, the control output uses NPN open collector signals rated at 100 mA maximum and 40 VDC or less. The unit also delivers ion level warning, condition warning, and alarm output for safe operation. For air-assisted use, the air connection port is Rc 1/8, with a recommended pressure of 0.2 MPa (range 0.1 to 0.5 MPa). Moreover, the installation distance spans 50 mm to 2000 mm, which fits many line layouts. The ion balance stays at ±30 V when measured at 300 mm or more with 0.2 MPa air pressure.
Mechanical and Environmental Parameters
The total length of the Keyence SJ-E156H is 1520 mm. At a 50 mm installation distance, the effective static elimination range reaches 1620 mm. The electrode probes use tungsten, and the main body combines ABS, PBT, PP, LCP, PPS, SPS, and SUS. Additionally, the unit weighs about 1.75 kg. For environmental limits, operating temperature runs from 0 to +40 °C, and relative humidity stays between 35 and 85% RH without condensation. The overvoltage category is I, and the pollution degree is 2. However, this model carries no specific protection rating.
Installation and Integration Guidance
Installing the SJ-E156H requires a stable 24 to 36 VDC power source. First, mount the bar at a working distance between 50 mm and 2000 mm from the target. Next, connect the air tube to the Rc 1/8 port and set pressure to the recommended 0.2 MPa. Meanwhile, wire the static elimination stop input using an NPN open collector or dry contact signal. The control output can feed an external monitor for ion level and condition alarms. Finally, check ion balance after installation with a charged plate monitor to confirm optimal performance.

FAQ
Q1: What is the effective static elimination length of the SJ-E156H?
A1: The effective length is 1620 mm at a 50 mm installation distance. Therefore, the SJ-E156H suits very wide webs and long conveyor lines.
Q2: Can this ionizer run without compressed air?
A2: Yes, the Keyence SJ-E156H generates ions through corona discharge. However, adding air flow improves ion delivery speed and extends the effective range.
Q3: What power supply does the SJ-E156H need?
A3: The unit accepts 24 to 36 VDC ±10%. At 24 V it draws 700 mA, and at 36 V consumption drops to 500 mA.
Q4: How can I monitor ionizer health on the SJ-E156H?
A4: The SJ-E156H offers condition warning and ion level warning outputs. Route these NPN open collector signals to a PLC or indicator for real-time monitoring.
Q5: What shipping methods do you offer?
A5: We ship via Fedex, UPS, and DHL. Delivery usually takes 3 to 7 business days, depending on destination and customs clearance.
