Does the dimensional tolerance of sintered ferrite magnets affect the performance of smart door locks?

1. Eşleştirmeyi kur

Impact on lock body assembly: If the size tolerance of the sintered ferrite magnet is too large, it may cause it to be installed in the corresponding position of the smart door lock, and cannot be accurately matched with other components. For example, the size of the magnet mounting slot is designed according to standard tolerances, and the actual size of the magnet is outside the tolerance range, there may be too tight or too loose installation of the magnet. Too tight installation may cause the magnet to be damaged by extrusion during installation, and even cause the deformation of the installation slot. If the installation is too loose, the magnet will shake inside the lock body, affecting the overall stability of the door lock

Magnetoresistive sensors are usually used in smart door locks to detect the switching state of the door, etc., and the magnet and sensor need to maintain a suitable distance and relative position to accurately work. If the dimensional tolerance of the magnet does not meet the requirements, it may lead to changes in the distance between the magnet and the sensor, which exceeds the effective detection range of the sensor, thus affecting the accurate judgment of the sensor on the door state, misjudgment or failure to detect the situation.

Large dimensional tolerances may cause changes in magnetic field strength and uneven magnetic field distribution, which affects the unlocking, locking operation and smoothness of use of the door lock. It also reduces reliability and durability. Magnets with inappropriate size are more susceptible to vibration, shock and other effects during use, and problems such as wear and rupture occur.
