Polymagnet
Part Number: 1000320
Pairs with: 1000320
Overview

These Attach Polymagnets are designed to have maximum attachment force in both magnet to magnet and magnet to metal applications. Made from Neodymium magnetic material, these magnets exhibit increased attach force and shear strength compared with their conventional counterparts. The Attach magnetic field is focused close to the face of the magnet resulting in higher peak force and a steeper force vs. distance curve. This allows magnetic systems to be tightly controlled to minimize stray fields that interfere with sensitive devices. For more details visit www.polymagnet.com/blog/Attach.

Application Notes

These Polymagnets provide very strong attachment forces to steel or their mating Polymagnet over their effective range compared to conventional magnets. These magnets are suitable for use with a metal target or another 1000320. A pair of 1000320 Polymagnets demonstrates a strong shear resistance against a force along their length and width. This shear resistance can be used to improve holding characteristics or transfer a lateral force across a gap.

The primary face of these magnets is marked during production. The markings must be facing the target steel for magnet to metal applications for proper performance. Likewise the markings must be aligned and facing each other in magnet to magnet applications. The holding strength can be enhanced in many applications by using a thin steel shunt directly against the back of the Polymagnet.

Notes on Performance Data
The performance information provided in this data sheet is derived from test or simulation results of directly comparable magnets of the same size and grade under consistent conditions. The magnets are tested under controlled environmental conditions. Unconstrained application testing may give lower forces due to the magnet tilting or shifting away from target during engagement and disengagement.
Customization Options
Polymagnets can be engineered to optimize behaviors and forces for specific applications. Different holding forces as well as alignment characteristics and release behaviors are also available as options. This typically involves varying the size, shape, and grade of the magnet in addition to the custom engineering of the Polymagnet pattern. Visit www.polymagnet.com/blog/custom for more details.
