Latch Magnets
Controlled magnetic attach and release functions
Push-Latch Smart-Mag®
Push-Latch programmed magnets are produced in matched pairs and will repel until they pass through the zero-force transition point - a specific and pre-determined distance - where they will then attract and attach. They do not have a bias to axially align, so they must be mechanically constrained to perform properly.
Twist-Latch Smart-Mag®
Twist-Latch magnets are similar to Push-Latch magnets, as they will repel until they pass and/or rotate through, the zero-force transition point where they will attract and attach. They differ by having an alignment pattern that will repel or release the magnets when one magnet is rotated into a specific orientation. The angle of rotation can be varied as well as the balance of attract and repel forces.
