Characteristics of Electron Beam Welding of Manganese Copper Shunts of Magnetic Latching Relays
1) The energy density of electron beam welding is high, and it can weld welds that are difficult to achieve by ordinary arc welding;
2) Electron beam welding is carried out in vacuum, the chemical composition of the weld is stable and pure, the joint strength is high, and the weld quality is high;
3) The electron beam welding speed is fast, the heat affected zone is small, and the welding thermal deformation is small;
4) Electron beam welding is suitable for welding almost all metal materials, especially for Copper Alloy Shunt and aluminum welding;
5) Electron beam welding can obtain welds with a large aspect ratio (20: 1 ~ 50: 1), and when welding thick parts, it can be formed at one time without opening the groove;
6) Electron beam welding combines computer technology to achieve precise control of process parameters and fully automate the welding process.
Electron beam welding technology is currently the fastest growing and most widely used electron beam technology.
We can supply samples of Latching Relay Manganin Shunt
We are a professional manufacturer of Manganese Copper Shunts for magnetic latching relays (also known as manganese-copper sampling resistors) for 15 years. The product has stable resistance value and good performance, and constantly develops and develops new structures. Especially in recent years, there are more and more embedded manganin resistors.
The Cable Wire Shunt Resistor produced by our factory have various specifications: 120 μΩ, 175 μΩ, 200 μΩ, 250 μΩ, 300 μΩ, 350 μΩ, 400 μΩ, 500 μΩ, 600 μΩ, 800 μΩ, 1000 μΩ and other resistance values, the resistance tolerance is ±5% , the hole distance and hole diameter are determined by the customer, and are suitable for various electric energy meters of different currents.
What is a Latching Relay ?
Magnetic latching relay is a new type of relay developed in recent years, and it is also an automatic switch. Like other electromagnetic relays, it automatically switches on and off the circuit. The difference is that the normally closed or normally open state of the magnetic latching relay is completely dependent on the action of the Permanent Magnet Shunt, and the switching of its switching state is triggered by a pulsed electrical signal of a certain width.
Magnetic latching relays are divided into single-phase and three-phase. According to relevant information, the Electric Silver Contact switching current of magnetic latching relays on the market can reach up to 150A; the control coil voltage is divided into DC9V, DC12V and so on. The general electrical life is 10,000 times; the mechanical life is 1,000,000 times; the Electrical SIlver Contact Rivet voltage drop of the contact is less than 100mV. Therefore, Brass Terminal Lead Shunt Resistor of latching relay has the characteristics of power saving, stable performance, small size, large carrying capacity, and superior performance than general electromagnetic relays.
