磁性组件、速度传感器、速度

•H101 Gear Tooth Sensor use a magnetically biased differential hall effect integrated circuit (IC) to accurately sense movement of ferrous metal targets. This specially designed IC, together with protection circuitry and a permanent magnet, is sealed in a probe type plastic package.

•The flux density of the permanent magnet alters when approached by ferrous metal. This is detected by the Hall IC. If the sensor is positioned at the circumference of a revolving gear wheel, for example, it detects teeth and tooth spaces, supplying a digital pulse output with frequency proportional to gear wheel speed. Optimum performance is dependent on the following variables which must be considered in combination: target material, geometry and speed, sensor/target gap, ambient temperature and stray fields.

•The sensor is flange mounted with a range of possible length, eliminating adjustment and positioning. Connection is by AMP 1-827578-1 connector.
