The Keyence SJ-E180L belongs to the energy-saving SJ-E series of static eliminators. This bar-type unit features a low-flow design that effectively neutralizes static charge across a broad effective length of 1880 mm. It utilizes a pulse AC corona discharge method with a ±8000 V applied voltage to generate ions reliably.
Ion Generation and Control
The SJ-E180L employs a shockless resistive coupling structure for safe operation. Its Hi-Power I.C.C. (Ion Current Control) system actively monitors and adjusts ion output. This closed-loop control maintains a precise ion balance of ±30 V, measured at an installation distance of 300 mm or greater with 0.2 MPa air pressure.
Electrical and Connectivity
Power requirements range from 24 to 36 VDC with a current draw of 700 mA at 24 V or 500 mA at 36 V. Control inputs include a static elimination stop function compatible with NPN open collector or dry contact signals. Outputs provide NPN open collector alarms for ion level, condition, and general alarm status, rated at 100 mA maximum. Remote control communication is supported for parameter adjustment and status monitoring.

Proper mounting ensures optimal performance of the SJ-E180L ionizer. First, position the bar within the specified installation distance of 50 to 2000 mm from the target surface. Next, secure the unit using the designated mounting brackets and ensure the air connection port (Rc 1/8) is fitted with a clean, dry air supply. Specifically, set the supply pressure to the recommended 0.2 MPa for rated ion balance performance. Finally, connect the 24-36 VDC power and control wiring according to the pinout diagram in the official manual.

Q1: What is the primary advantage of the low-flow design in the SJ-E180L?
The low-flow model reduces air consumption by approximately 60% compared to conventional models. It achieves this through a supersonic structure that accelerates ion delivery without requiring high air volume.
Q2: Can I monitor the SJ-E180L's performance remotely?
Yes. The unit supports remote control communication. This function allows operators to check ion balance status and alarm information from a compatible remote controller.
Q3: What type of maintenance is required for this ionizer?
The tungsten electrodes typically require minimal maintenance due to the air curtain effect. However, periodic cleaning of the probe tips is recommended depending on the operating environment. Always disconnect power and air supply before servicing.
Q4: Is the SJ-E180L suitable for cleanroom applications?
The unit has a pollution degree rating of 2 and operates within 35-85% RH without condensation. While it is not explicitly rated as a cleanroom-specific device, it is commonly used in ESD-controlled areas for electronics manufacturing.
Q5: What is the typical lead time and shipping method?
We ship via Fedex, UPS, and DHL. In-stock items typically dispatch within 1-2 business days. Please confirm current availability with our sales team before ordering.
