Keyence SJ-L005F Compact Fan Static Eliminator — Wide-Area Ioniser with Alarm Output

Keyence SJ-L Series · AC-Pulse Ioniser · Static Discharge for Assembly Lines

The Keyence SJ-L005F is a compact fan-type static eliminator (ioniser) from Keyence's SJ-L series. The unit combines a built-in cross-flow fan with an AC-pulse corona discharge electrode to neutralise static charge on parts, films, and trays passing under the airflow. The "F" suffix denotes the alarm-output variant: an NPN / PNP alarm signal is asserted when ion emission drops below a healthy threshold, which the line PLC reads as a predictive-maintenance input — typically a Mitsubishi MELSEC, Keyence KV, or Allen-Bradley MicroLogix.

At koeed.com we list the SJ-L005F as an ESD-control consumable for electronics assembly, plastic-parts handling, film / sheet converting, and pharmaceutical packaging. The emitter pin and the air filter are the wear parts; the body itself is usually replaced only when the alarm output flags a failure, or when a keyence-SJ legacy line is being refreshed.

Key Specifications

Datasheet Highlights

• Built-in cross-flow fan means the unit can be installed with no compressed-air supply — ideal for cell-side or conveyor-side installation where an air line is not available.
• AC-pulse corona discharge gives balanced positive / negative ion emission, which is the right method for high-decay-rate, low-residual-voltage applications on plastic parts and films.
• "F" alarm-output variant asserts a digital signal when the emitter pin wears past a healthy threshold — that signal can be tied into a PLC input for predictive maintenance, which is the right way to manage a fleet of ionisers on a long line.
• Emission-balance calibration at the factory means out-of-the-box performance matches the published decay-time spec — important when the cell is in a regulated ESD-control program (ANSI/ESD S20.20, IEC 61340-5-1).
• Removable emitter-pin cartridge and air-filter element can be replaced as a PM, extending the life of the body well past the typical 2-3 year maintenance cycle.
• 24 VDC supply is shared with the rest of the cell — the SJ-L005F drops onto the same Phoenix Contact or Meanwell 24 VDC bus that feeds the PLC and the I/O.

Typical Applications

• Electronics assembly: PCB and component-handling cells where static-discharge damage is the leading cause of latent field failures.
• Plastic-parts feeding: pick-and-place cells handling moulded parts, where static causes parts to stick to the gripper or fly off the conveyor.
• Film & sheet converting: unwinding and slitting lines where static attracts dust and causes the web to wander.
• Pharmaceutical packaging: blister-pack and bottle-filling lines where the regulatory ESD-control program requires a documented decay-time target.
• Cleanroom cells: semiconductor and display fabs where the SJ-L005F provides balanced ionisation without a particle-generating compressed-air supply.
• Vision-system stations: Keyence CV-X / IV3 inspection cells where a static charge on the part can deflect a laser-line profile and cause false rejects.

Related Modules & Cross-Reference

Static-control is a cell-level concern, so the SJ-L005F is normally purchased alongside the PLC that reads the alarm output and the vision system that depends on the static-free environment. KOEED can ship the SJ-L005F with that wider cell kit:
