Pairs with: 1000319
Align Polymagnets are engineered with a selective pattern that gives them a stronger holding force and unique alignment characteristics compared to conventional magnets. Standard magnets typically do not align with any level of precision when attaching to each other and do not have a preference for their rotational orientation to another magnet. These Polymagnets are designed provide a high holding force when aligned and very little attractive force when out of alignment. As these magnet approach alignment they provide a positive force toward the alignment position. This allows products and systems to be engineered with alignment behaviors that give them a unique user experience. Align Polymagnets also exhibit a tightly controlled magnetic field that minimizes interference with sensitive devices. For more details visit www.polymagnet.com/blog/align.
These Align Polymagnets provide superior linear alignment attributes compared to conventional magnets over their working range. A pair of 1000319 Polymagnets demonstrates a strong force toward their alignment position when offset on their long axis. These magnets can be used to align and attach components or accessories. By using multiple pairs in different arrangements the components can be made reversible or restricted to a particular orientation. These magnets can also be used to transfer a linear force across a gap. The alignment force as a function of lateral offset can be seen in the graph below at a separation distance of 1.5mm.
When two 1000319 Polymagnets are laterally offset their attractive force decreases while their centering force increases. The operating regions with small or negative holding force and a positive centering force give the magnets a self-aligning effect. This can be used to improve performance and user experience in many applications.
The primary magnet face is marked during production. The markings must be aligned and facing each other in the application for proper performance. The holding strength can be enhanced in many applications by using a thin steel shunt directly against the back of the Polymagnet, and this shunt will also help limit stray fields from the magnet.
