Manufacturer:NS Description: Figure 3 relates the output state of a back-biased sensor IC, with switching characteristics shown in Figure 2, to the target gear profile and position. Assume a north pole back-bias configuration (equivalent to south pole at the face of the device). The motion of the gear produces a phase-shifted field at E1 and E2 (Figure 3 (a)); internal conditioning circuitry subtracts the field at the two elements (Figure 3 (b)); and the Schmitt trigger at the output of the conditioning circuitry switches at the pre-determined thresholds (BOP and BRP). As shown (Figure 3 (c)), the IC output is LOW whenever sensor E1 sees a (ferrous) gear tooth and sensor E2 faces air. The output is HIGH when sensor E1 sees air and sensor E2 sees the ferrous target. |
