Not true. Hall and MR sensors are DC sensitive devices. From 1984

A Hall effect device is sensitive to a stationary magnetic
field, unlike a coil of wire, which requires a moving

Subject: [Emc-users] Magnetic Geartooth Sensor for Spindle
Has anyone tried using a magnetic sensor such as a crankshaft position
sensor for a spindle encoder? I would not have to protect this
arrangement nearly so well as an optical system against oil

So the short message is: Keep your hall effect devices scrupulously clean.

As above, I am aware that halls have been used to good effect as engine
