Pulse AC Area Static Eliminators: Wide-Area Neutralization on High-Speed Transfer Systems
Pulse AC static eliminators generate alternating positive and negative ions from single tungsten electrodes via frequency-modulated high-voltage corona discharge. This mechanism extends ion dispersion distance to 300 mm while maintaining ion balance within ±30 V, solving residual static charge on relay terminals during continuous high-speed transfer.
Physics of Pulse AC Discharge: Frequency control for long-distance ion dispersion
Pulse AC technology adjusts discharge frequency from 1 Hz to 100 Hz to regulate ion cloud density. Low-frequency settings produce wide-spread ion flux for long-distance neutralization; high-frequency modes concentrate ions for short-gap, high-cycle pick-and-place stations.
Panasonic ER-X Series Hardware Specifications
The ER-X series adopts dual-emitter bar configurations and compressed air assist nozzles. Compressed air at 0.05 MPa pushes ion clouds toward workpiece surfaces, cutting static decay time below 0.5 s.
