Good magnetic sensors in disk drives , brushless DC motors or Car ignitions use Hall Effect sensors that provide a solid state or linear output with a change in magnetic field. Usually a notch or hole is sensed. Cheaper sensors use magnetic switches when the contact frequency is low. REED RELAYS are such a device. dino@inqmind.bison.mb.ca The Inquiring Mind BBS, Winnipeg, Manitoba 204 488-1607
