Hall effect sensors

Hall effect sensors Hall effect sensors are becoming a key technology for motor control and appliances. The effect provides a low-cost combination of both sensing and switching that simplifies the cost and implementation of design, but can also open a new design opportunities. For example, using the magnetic-sensing capabilities and integrating orthogonal Hall sensors can produce an effective low-cost compass.

The device also has the ability to sense fields that are shielded by non-ferrous materials, providing key advantages in areas such as motor control. Several different types of Hall Effect devices are available, suitable for applications ranging from switches and linear magnetic field sensors to current sensor ICs and devices that can detect speed and direction.
