Application68 Analysis or Reed Relay

"Reed relay is used in various types of control circuits.
The basic configuration of a reed relay consists of a reed switch and a coil that gives magnetic excitation from outside. It covers areas of semconductor switche and electromagnetic relay."

With coupled analysis of electromangnetic and stress, the deformation due to the electromagnetic force can be analyzed. A coil is placed over the reed relay and energized. The contact/contactee boundary condition is applied to the two reeds to execute the stress analysis. The electromagnetic force is generated on the reeds by the current that attracts the reeds each other. By replacing the current of coil with magnet, MR sensor can be analyzed as well.
