Description
We offer a range of permanent magnets for customers using our products. They come in different sizes and shapes, and are specially selected to meet critical actuation distance applications. Five sizes of cylindrical and Rectangular magnets are available, magnetized longitudinally, as shown in the drawings. They have a low strength variation tolerance band as a batch to ensure your actuation distance requirements are met.
