Bunting-DuBois’s expertise in assisting customers in material and magnet selection for sensors, particularly those used in critical applications, is unmatched. Magnetic sensors are vital components in many different items, and drive the technology behind phones, computers, vehicles, and other products critical to everyday life.
Magnetic sensors are used in critical applications that drive the economy, facilitate rapid communication and transport of goods and people, and keep us safe in our everyday lives.
A magnetic sensor works by converting magnetic or magnetically encoded information into electrical signals. Then, electronic circuits process this information. In a magnetic sensor, a permanent magnet’s role is to provide a magnetic field in an air gap, which can be either constant and extremely precise or highly variant in direction and magnitude. For example, sensors in a standard vehicle are able to detect a vehicle’s velocity, position, and directional movement. Magnetic sensors are able to operate with no need for contact, meaning that there is no physical wear or tear to the sensor. They are able to work through sealed barriers while maintaining high reliability in performance, making them an extremely valuable piece of technology.
Magnetic sensors are used in critical applications to measure a variety of essential variables, such as rotation angle, alignment, field strength, direction, proximity, and speed. In order to perform at their highest level, a magnetic sensor must be evaluated for several factors, including its sensitivity, selectivity, reliability, environmental resistance, self-adaptability, size, weight, resistance against overload, and power consumption. When designing a magnetic sensor, it is important to select the optimal magnetic material as well as to create an optimally designed sensor.
Engineering the optimized magnet for a sensor in a critical, highly specialized application is challenging, but Bunting’s team of engineers is the best equipped to handle the task. At Bunting, we utilize 2D and 3D computer modeling software to optimize permanent magnets for applications. When determining the optimal magnet for your application, our engineers analyze a full range of factors, including magnet grade, optimized geometry, temperature and humidity, mechanical requirements such as electrical conductivity and air gap, and countless other variables related to a magnetic sensor’s performance.
