Keyence SJ-E108H Ionizer Bar 1040mm

Keyence SJ-E108H Static Eliminator: High-End Bar Ionizer for Industrial Static Control

Product Introduction

The Keyence SJ-E108H belongs to the SJ-E series of high-end bar-type static eliminators. This model utilizes a corona discharge method with a shockless resistive coupling structure. Specifically, it applies a pulse AC voltage of ±8000 V to generate ions efficiently. The Hi-Power I.C.C. method maintains ion balance within ±30 V under standard conditions. As a result, this model suits production lines that require rapid static neutralization across wide surfaces. Furthermore, the 33 tungsten electrodes and 1140 mm effective length enable consistent performance over a large target area.

Technical Specifications and Performance Features

The SJ-E108H operates on a 24 to 36 VDC power supply with a current consumption of 700 mA at 24 V or 500 mA at 36 V. Besides, the control output supports NPN open collector signals with a maximum of 100 mA at 40 VDC or less. The unit provides ion level warning, condition warning, and alarm output functions for safe operation. For air-assisted applications, the air connection port is Rc 1/8, and the recommended supply pressure is 0.2 MPa (operating range 0.1 to 0.5 MPa). Moreover, the installation distance ranges from 50 mm to 2000 mm, offering flexibility for different production setups. The ion balance remains stable 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-E108H is 1040 mm, while the effective static elimination range measures 1140 mm at a 50 mm installation distance. The electrode probes use tungsten material, and the main body consists of ABS, PBT, PP, LCP, PPS, SPS, and SUS. Additionally, the unit weighs approximately 1.30 kg. For environmental tolerance, the operating temperature ranges from 0 to +40 °C, and the relative humidity range is 35 to 85% RH without condensation. The overvoltage category is I, and the pollution degree is 2. However, this model does not carry a specific protection rating.

Installation and Integration Guidance

Installing the SJ-E108H requires a stable 24 to 36 VDC power source and a clean air supply if air purge is needed. First, mount the bar at the desired distance between 50 mm and 2000 mm from the target surface. Next, connect the air tube to the Rc 1/8 port and set the pressure to the recommended 0.2 MPa. Meanwhile, wire the control input for static elimination stop using an NPN open collector or dry contact signal. The control output can connect to an external monitoring system for ion level and condition alarms. Finally, verify the ion balance after installation using a charged plate monitor to ensure optimal performance.
