They're a variety of magnetic sensor that makes use of a material property called the Wiegand effect. I'm not sure of the details (though I could dig some up), but the essence of the matter is that when the magnetic field passing through the sensor changes polarity, the sensor puts out a fixed magnitude voltage pulse (the ones I saw were 2V). The pulse magnitude is independent of the rate at which the polarity change occurs. The sensors we bought have the added benefit of working to temperatures of 200 degrees C, beyond the range of semiconductor based (Hall) sensors. I've got more information. If you're interested, you can send me E-mail (macminn@crd.ge.com).
