ABS and ABN brakes are commonly called  'safety brakes'  because they will stop a rotating shaft even if power is cut off. They are widely used in automatic hoists, conveyors, cranes, winders and automated storage systems to stop operations there materials are being transported vertically or horizontally. Other applications include machine tools, especially automatic lathes and vertical lathes, to stop and hold moving parts on the work table.

When the ABS is under load (non-magnetized) in a magnetic brake, its design causes the spring of the coil to hold the brake piece in place and create braking torque through its friction. When the coil is energized and magnetized the armature with its primary brake piece is compressed further and the magnetic core is attracted so that braking action stops.
If the magnetic current is cut off the tension of the coil spring will cause the armature to hold the brake piece in place so that the brake is activated.

item-01.gif Safe and secure control
  Steady torque levels for fast control of loads even in abnormal conditions. This is a highly reliable and safe type of clutch.
item-02.gif Quiet action
  This brake has no bothersome high pitched whine and can be used in the quietest locations with no problems.
item-03.gif Adjustable torque
  Shifting the adjustable band changes the amount of torque; moreover, the dual drive design reduces torque levels significantly for the safest possible operation.
item-04.gif Dust cover
  A plastic cover on the ABS model ensures reliable operation even in the dirtiest environment.
item-05.gif Manual release
  Braking action can be obtained even under load by pulling the release lever (ABS model).
item-06.gif Long life
  Durable friction materials mean long useful life with no need fr changes.
item-07.gif Easy assembly and adjustment
  The unit is fast and simple to install and adjust
