Differential Hall Effect Sensor

No offset shift over the target features.

Differential hall effect sensor.

The hall effect is an ideal sensing technology. The tle4926c ht e6547 is an active hall sensor suited to detect the motion and position of ferromagnetic and permanent magnet structures. These characteristics make the series of a5s sensors especially suited to all applications where high levels of accuracy and reliability are at a premium. A multitude of devices vehicles tools and equipment possess rotating elements such as motors gears and teethed targets.

The hall element is constructed from a thin sheet of conductive material with output connections perpendicular to the direction of current flow. Differential hall effect sensors aid rotational speed control. In many instances the rotational speed of these elements needs to be monitored and or controlled to ensure proper system performance. Their low end of 0 hz allows monitoring the machine down to zero speed.

The sensing element is a magnetically biased hall device followed by an amplifier having a trigger characteristic and short circuit proof output stage. Its output voltage is directly proportional to the magnetic field strength through it. The differential hall effect gear tooth sensor cygts9921 provides a high sensitivity and a superior stability over temperature and symmetrical thresholds in order to achieve a stable duty cycle. The signal shape is roughly sinusoidal with up to two times the peak to peak magnetic field figure 2.

They exhibit a dynamic function whereby pulse generation down to 5 hz is guaranteed. A hall effect sensor is a device that is used to measure the magnitude of a magnetic field. They are contact free wear free maintenance free and unsusceptible versus external magnetic stray fields and machine vibration. When subjected to a magnetic field it responds with an output voltage proportional to the magnetic field strength.

Safety noticethe speed sensors dsf xx10 xx xhv ex atex are certified for applications in areas with explosive atmospheres. Differential hall effect sensor differential hall effect sensors detect target edges. These types are to be duly used in undamaged and clean condition. Our a5s speed sensors are based on the proven differential hall effect principle.

Frequently a hall sensor is combined with threshold detection so that it acts as and is called a.
