Process introduction
Magnetic latching relay is an automatic switch.Like other electromagnetic relays, the circuit is automatically switched on and off.The difference is that the normally closed or normally open state of the magnetic latching relay is completely dependent on the action of permanent magnetic steel, and its switching state is triggered by a certain width of pulse electrical signal to complete.
When the contact of the relay needs to be on or off, it only needs to excite the coil with positive (reverse) dc pulse voltage, and the relay completes the state conversion of on and off in an instant.Normally, when the contact is in the holding state, the coil does not need to continue to be energized, and only the magnetic force of the permanent magnet can maintain the state of the relay.
The material of contact will choose silver stannous indium oxide to cooperate with different material to use commonly
This type of relay contact is relatively large, the general specification is 5mm，5.5mm，6mm，6.5mm，7mm，the silver layer of its rivet thickness will be relatively thick，
Production capacity
Because the contact is relatively large, so the production speed will be slow, a machine can only produce 30,000 a day
Packaging and service
we have a special grinding and polishing process for the post-treatment to ensure that the contact is free of burr and copper chips. At the same time, we use imported contact protective agent to improve the contact resistance
The packing method of the contact is vacuum, the contact is in line with the international environmental protection ROHS and REACH standards, the packaging bag is in accordance with ROHS and REACH standards for purchase
Quality guarantee
The raw materials of each batch will be selected during the incoming inspection, and the daily production status will be recorded during the process inspection and finished product inspection to ensure the qualified rate
