Keyence SJ-E132A Static Eliminator Bar

Product Introduction

The SJ-E132A is a standard bar-type static eliminator from the Keyence SJ-E series. This model generates ions through a pulse AC corona discharge method with ±8000 V applied voltage. Moreover, the Hi-Power I.C.C. (Ion Current Control) system actively adjusts ion output and keeps ion balance within ±30 V. The unit carries 21 tungsten electrode probes and provides an effective static elimination length of 1380 mm at a 50 mm distance. In addition, the shockless resistive coupling structure improves operator safety. This ionizer suits wide production lines such as film coating, packaging, printing, and electronics assembly, where static charge causes dust attraction or discharge damage.

Technical Specifications

The SJ-E132A runs on a 24 to 36 VDC ±10% power supply. Current consumption is 700 mA at 24 V and 500 mA at 36 V. Ion generation uses the corona discharge method combined with pulse AC voltage application. Specifically, the Hi-Power I.C.C. method compensates for electrode wear and environmental changes in real time. The rated ion balance is ±30 V, measured at 300 mm or more with 0.2 MPa air pressure. Meanwhile, the installation distance spans 50 to 2000 mm, so the bar fits many line layouts. All 21 electrode probes use tungsten, a material selected for durability and resistance to spark erosion.

Communication and Electrical Data

This model has no built-in communication ports. However, remote control communication is supported through optional remote controllers. The output type is NPN open collector, covering ion level warning, condition warning, and alarm output. Besides, the control input accepts a static elimination stop signal from an NPN open collector or a contact point. The control output is also NPN open collector with a maximum of 100 mA at 40 VDC or less. Air connects through an Rc 1/8 port, and the recommended supply pressure is 0.2 MPa within a 0.1 to 0.5 MPa range. The overvoltage category is I, and the pollution degree is 2.

Mechanical and Environmental Parameters

The total length of the bar is 1280 mm, while the effective static elimination range reaches 1380 mm at a 50 mm distance. The main body uses ABS, PBT, PP, LCP, PPS, SPS, and SUS materials. The unit weighs about 1.50 kg. Operationally, the SJ-E132A works within 0 to +40 °C and 35 to 85% RH without condensation. No protection rating is assigned to this model. Therefore, install it inside a clean enclosure when dust or splashing water is present.

Installation Guide

First, mount the bar with the supplied brackets at the target position on the line. Next, wire the unit to a 24 to 36 VDC source and confirm the polarity. The stop input accepts an NPN open collector or a dry contact signal. For air-assisted use, connect the Rc 1/8 fitting to clean, dry air and set the regulator to 0.2 MPa. Furthermore, keep the bar 50 to 2000 mm from the material for best results. Finally, check the alarm and warning outputs after power-up, then adjust the ion balance as needed.

FAQ

Q1: What is the effective static elimination length of the SJ-E132A?
A1: The effective length is 1380 mm at a 50 mm installation distance. The actual range depends on distance, air pressure, and ambient conditions.

Q2: How many electrodes does this bar carry?
A2: The SJ-E132A carries 21 tungsten electrode probes. This count matches its 1280 mm total length and 1380 mm effective range.

Q3: Does the SJ-E132A include built-in communication ports?
A3: No, this model has no built-in ports. Remote control communication works through optional remote controllers from the SJ-E series.

Q4: Can the ionizer run without compressed air?
A4: Yes, it generates ions without air. Nevertheless, clean air at 0.2 MPa speeds ion delivery and helps keep the electrodes clean.

Q5: What power supply does the SJ-E132A require?
A5: The unit needs 24 to 36 VDC ±10%. Current draw is 700 mA at 24 V or 500 mA at 36 V, so size the supply with margin.
