SJ-E180H Bar Type Ionizer Technical Guide
Product Introduction
The Keyence SJ-E180H functions as a bar-type main unit within the energy-saving SJ-E ionizer series. Firstly, it utilizes a corona discharge method with a shockless resistive coupling structure. This design specifically targets wide-area static removal on production lines. Furthermore, the unit features a total length of 1760 mm and incorporates 57 tungsten electrode probes. Therefore, engineers select this model for continuous, high-speed static neutralization in manufacturing environments.
Core Value
The SJ-E180H delivers substantial operational value through its Hi-Power I.C.C. (Ion Current Control) method. Specifically, this technology maintains ion balance within ±30 V to prevent reverse charging or particle attraction. In addition, the pulse AC method applies ±8000 V to generate ions rapidly. Meanwhile, the unit achieves an effective length of 1860 mm when installed at a 50 mm distance. Consequently, a single SJ-E180H replaces multiple smaller static bars, which reduces both wiring complexity and maintenance points.
Technical Insights
Operators configure the SJ-E180H for an installation distance ranging from 50 mm to 2000 mm. The unit accepts a 24 to 36 VDC power supply and draws 700 mA at 24 V. Moreover, the air connection port uses an Rc 1/8 thread with a recommended supply pressure of 0.2 MPa. This air assist function blows ions toward the target surface for faster decay times. Besides, the control output provides NPN open collector signals for ion level warnings and condition alarms. Remote control communication further enables centralized parameter monitoring without local access.
Installation & Maintenance
Firstly, mount the SJ-E180H rigidly at the specified distance from the target material. Ensure the ambient temperature remains between 0 and 40°C with humidity below 85% RH without condensation. Secondly, connect the air line and set the regulator to 0.2 MPa. The shockless resistive coupling design protects operators from electric shock during normal operation. Furthermore, periodically clean the 57 tungsten electrode probes with a soft brush to remove accumulated dust. Besides, verify the ion balance monthly using a charged plate monitor. If the condition alarm activates, inspect the electrode area and air supply immediately.
