Keyence SJ-E084H Ionizer | 800mm Bar Type

Keyence SJ-E084H High-End Bar Ionizer for Wide Production Zones

Product Introduction

The Keyence SJ-E084H fills the gap between compact and long-reach bars in the SJ-E high-end family. Specifically, its 800 mm body and 25 tungsten electrodes cover a 900 mm effective span. This makes it a practical choice for wide webs, coating lines, and larger assembly stations. Furthermore, the Hi-Power I.C.C. method maintains ion balance within ±30 V, so charge-sensitive products stay protected throughout the process.

Technical Specifications

Ion Generation and Control
This model uses the corona discharge method with a shockless resistive coupling structure. Additionally, it applies a pulse AC voltage of ±8000 V to generate balanced positive and negative ions. Ion balance control depends on the Hi-Power I.C.C. method. Meanwhile, measured ion balance remains within ±30 V at 300 mm distance and 0.2 MPa air pressure.

Electrical and Connectivity
Supply voltage ranges from 24 to 36 VDC ±10%. Current consumption is 700 mA at 24 V or 500 mA at 36 V. The output stage delivers NPN open collector signals for ion level warning, condition warning, and alarm. Besides, a static elimination stop input accepts NPN open collector or contact point wiring. Remote control communication is supported for parameter checks and status reading.

Air and Electrode System
An Rc 1/8 air connection port accepts supply pressures from 0.1 to 0.5 MPa, with 0.2 MPa recommended. The 25 electrode probes use tungsten material for long service life. Furthermore, the effective static elimination range measures 900 mm when the bar sits 50 mm from the target.

Mechanical and Environmental Parameters

The Keyence SJ-E084H operates from 0 to +40°C and tolerates 35 to 85% RH without condensation. Its main body combines ABS, PBT, PP, LCP, PPS, SPS, and SUS materials. At 1.10 kg, the bar remains light enough for standard mounting brackets on frames and conveyors. Finally, the overvoltage category is I and pollution degree is 2.

Installation Guide

Installing the SJ-E084H follows a clear sequence. First, mount the bar between 50 and 2000 mm from the target surface. Next, connect clean, dry air to the Rc 1/8 port and regulate pressure to 0.2 MPa. Then, wire the 24–36 VDC supply and NPN open collector control lines. Subsequently, verify ion balance with a charged plate monitor. Finally, activate remote control communication if centralized monitoring is needed.

FAQ

Q1: What is the effective static elimination length of the SJ-E084H?
A: The effective length is 900 mm at a 50 mm installation distance. This covers wide webs, coating lines, and larger assembly stations.

Q2: How many electrodes does this bar ionizer contain?
A: The unit carries 25 tungsten electrode probes along its 800 mm body. This spacing supports even ion coverage across the 900 mm working span.

Q3: Does the SJ-E084H need compressed air to operate?
A: Yes. Airflow carries the generated ions to the target surface. Connect clean, dry air at 0.1 to 0.5 MPa, with 0.2 MPa recommended for rated balance.

Q4: What output signals does the SJ-E084H provide?
A: It offers NPN open collector outputs for ion level warning, condition warning, and alarm. Each output handles up to 100 mA at 40 VDC or less.

Q5: What are the weight and power figures for the SJ-E084H?
A: The unit weighs 1.10 kg. Current draw is 700 mA at 24 VDC or 500 mA at 36 VDC, within a ±10% supply tolerance.
