Magnet Sensors have become an indispensable tool in various industries due to their ability to detect and measure the presence and position of magnetic fields. Understanding the distance capabilities of these sensors is crucial in ensuring optimal performance and accurate measurements.

Generally, the distance at which a magnetic sensor can detect a magnet's magnetic field decreases as the size or strength of the magnet decreases. The larger the magnet, the wider the sensing distance. Conversely, the smaller or weaker the magnet, the shorter the sensing distance.

Other important factors to consider are the sensor's sensitivity and the material surrounding the magnet. Magnetic sensors with higher sensitivities can detect smaller magnetic fields from a greater distance. Additionally, materials such as iron and steel can affect the sensing distance by altering the magnetic field's strength.

It is crucial to highlight that the sensing distance mentioned in the specifications of a Magnet Sensor is typically measured based on a specific configuration under ideal conditions. Real-world applications, however, may involve variations such as ferro-magnetic parts in the vicinity that can impact the sensor's performance.

To achieve the best results, it is recommended to consult the sensor manufacturer's guidelines and thoroughly understand the limitations and optimal conditions for the specific Magnet Sensor being used. Regular audits are also essential to ensure accurate distance measurements over time.

To help make AT band and Actuating Magnet Selection easier, we have listed various combinations of actuation and corresponding actuation magnets. These Magnetic  Sensor actuation distances will help select the right bands for use in your application.

Although some of the AT band / magnet combinations will produce similar actuating distances, selecting the right AT band and magnet for an application is important and can be done by going through our AT band Selection guide and our magnet selection guide. Please contact us for more information.
