发明名称 System to Test Magnetic Sensitivity of Hall-Effect Switch
摘要 A system and method for determining the magnetic sensitivity of a Hall-effect switch through the use of a variable powered DC electromagnet having a permanent magnet attached to it. In use the electromagnet is placed in contact with a Hall-effect switch component and the DC voltage varied until a detector determines the Hall-effect switch has been triggered. The electromagnet is then moved to be in contact with a probe connected to a Gauss meter to determine the magnetic sensitivity of the Hall-effect switch.
