HS (High-Speed) and HD (High Deflection) vibratory feeders feature low energy, AC electromagnetic drives to provide reliability, precise cycling and low operating cost. The high deflection series is recommended when feeding lightweight, loose or sticky materials where a higher deflection (3/16-in.) and lower frequency (30 cps) produces more accurate feed characteristics. Both HS and HD series use the same style AC drive, enabling systems to cycle up to 100 times/min.
