Annis 60 Hz AC Demagnetizers concentrate the demagnetizing field on the parts' surface with decreasing field strength with increased depth. Thin and low alloy / low hardness materials are more thoroughly demagnetized than solid and thick parts with high alloy / high hardness. When full cross section demagnetization is needed Low Frequency AC or Reversing DC is required - call us.
Annis Coil type Demagnetizers operate from a 60 Hz AC line. Custom aluminum housing is designed for surface / bench mounting and the "ribbed" outer surface enhances convective heat transfer. Annis demagnetizers have field strengths that range from 230 to 1,200 Gauss and are designed to operate in either continuous (C) or Intermittent (I) mode in dry environments. Units are available for operation in "non-dry" conditions. Intermittent types have a 25% duty cycle with a maximum "on" time of 5 minutes. Annis demagnetizers are currently used worldwide and are available in a wide variety of shapes, sizes and field strengths to fit your needs.
