- :Good magnetic sensors in disk drives , brushless DC motors or Car
- :ignitions use Hall Effect sensors that provide a solid state or linear
-
- :
- :Cheaper sensors use magnetic switches when the contact frequency is low.
- :REED RELAYS are such a device.

- my latest project needs a magnetic sensor to operate over a range
- from 0 to 100Hz. I think this is at best pushing the limit
- of what i can do with a reed switch. How can i find out
- out more about hall effect devices? A small quantity supplier,
- with data sheets would be nice..
