A magnetic latching relay
is a type of relay that has two layers. The upper layer consists of the electromagnetic system and the lower layer consists of the contact system. The electromagnetic system is made up of a direct-acting magnetic circuit system that uses a flat structure. The magnet is located at the center of the mounting plate, and coils are installed on either side. An iron core is arranged above the coils, and a ring-shaped armature is attached to the iron core. The magnetic field generated by these systems can control the armature.A magnetic latching relay is a switch that uses a signal from one circuit to switch to another. The switching process does not have to be synchronized with a direct electrical connection, which makes relays ideal for a variety of applications. They are simple to understand, versatile, and can be used in a variety of ways.Magnetic latching relays may have up to two sets of contacts. The first set of contacts has an N-polarity, while the second set is S-polarized. In either case, a pulsed electric signal is applied. When the pulsed electric signal is received, the first magnetic yoke 41 becomes S-pole-shaped.Mini Current Transformer37
The second magnetic yoke 42 is N-polarized, enabling the first S-side terminal 55 to be repelled by the first S-side terminal, while the second N-side terminal 52 is attracted to the second S-side terminal. When this happens, the magnetic steel assembly 5 is driven to deflect rightwards. As it does so, the magnets become more magnetized, stabilizing at the attraction state.A magnetic steel latching relay is a switching device in which the magnetic steel assembly is coupled with a latching device. The magnetic steel assembly includes two driving heads, which rotate synchronously with each other. The heads are mounted on the magnetic steel assembly in a contact fit. The synchronous rotation of the magnetic steel assembly is transferred to the latching device by a transmission chain.Magnetic latching relays include two layers, one on the upper side and one on the bottom.
The upper part consists of an electromagnetic circuit and the lower part comprises a contact system. The magnetic assembly includes a magnet, which is mounted in the center of the mounting plate, two coils, and an armature, which is attached to the armature through a rigid strut.Contact devices for magnetic latching relays can be designed for specific applications. These devices have multiple coils and are typically designed for industrial use. These devices may have a resistive contact rating of ten amps at 120 VAC or five amps at 240 VAC. In addition, they may have a twenty-millisecond maximum operating and release time and a clear polycarbonate enclosure. The contacts on these devices are designed to meet UL and CSA standards and military specifications.Magnetic latching relays can operate in single-phase or three-phase configurations. Their mechanical locking strength does not decrease with age or thermal cycling.
As long as the contacts are securely locked in the oriented location, the relay will remain locked in place until the opposite coil is strengthened. These devices are especially useful in more complex lighting plants.A magnetic latching relay comprises two guide transmission parts. These parts move along the swing direction of a movable flat spring, and they are connected to two contact devices and a magnetic steel assembly. The driving end of the first guide transmission part is connected to the driving head through a driving connection structure, while the other end is coupled to the free end of the movable flat spring through an elastic transmission structure. During the actuating operation of a magnetic latching relay, both of the guide transmission parts move in the same direction.
