Motor Latching Relay
Relay industry development has been nearly two hundred years old, are derived from the process of various types of relay, which keep the relay because of its since latching and low energy consumption, in not frequent on-off circuit applications，we can see it’s big player especially widely used in tariff-control meter, the electric car charging pile, street lamp control system.
At present, the latching relays mainly use magnetic latching and mechanical locking devices. In recent years, the motor latching relays have overcome many shortcomings of latching relays and started to enter the market as a new force of latching relays.When the magnetic latching relay is shaken by external force, it may have the problem of state switching. At the same time, because the contact pressure is not large enough, a slight change in the size of the contact may also cause great changes in the contact state or pressure. In addition, unless it equipped metal case,the magnetic latching relay may not work normally when it is interfered by external magnetic field.
The mechanical latching relay has been gradually eliminated from the relay market because of its complex structure, difficult assembly and inability to realize normal on-off when affected by external magnetic field interference. The traditional motor latching relay has a series of problems, such as large volume, high cost, short mechanical life, long operation time and so on. It can seldom realize normal on-off through simple structure stability.
This time we are talking about the small motor latching relay, its internal unique gear structure and special mode of transmission, can use a few copper to realize in the structure.In this case it can greatly save the use of copper materials, save the cost. At the same time, the structure characteristics make the contact pressure bigger, there is no secondary recovery, also won't share the contacts even current electromagnetic induction force, easily automated assembly and test automatically, greatly improve the efficiency.In addition, the design method of overtravel can ensure the consistency of the quality of the motor relay. The small motor’s iron shielding cover greatly improves the ability of the relay to resist the magnetic field, which can normally work in the magnetic field environment of 400mT or 500mT.Reasonable transmission design and motor collocation design, so that the relay disconnected and closed time, only dozens of milliseconds.
As a new face of latching relays, motor latching relays will be developed and applied in more industries with their excellent shining points in the near future, and the majority of demanders in the relay industry will also regard their characteristics and advantages and apply them in their project equipment.
