Products Description
The Shunt Terminal For Magnetic Latching Ralay 100A is made of copper and manganese copper strips integrally formed by electron beam laser welding and then processed by precision stamping. Its core function is to convert the large current of the magnetic latching relay into a measurable voltage signal, so as to realize accurate current measurement, overload protection and circuit monitoring. It is a key supporting component for the stable and efficient operation of the magnetic latching relay.
Material advantages
Extremely Low Resistance, Low Heat Loss
Manganese copper possesses excellent electrical conductivity. Combining the high conductivity of copper with the strengthening effect of manganese, the terminals generate extremely low heat when transmitting currents up to 100A, effectively preventing poor contact or burnout due to overheating for Manganin Shunt Resistor.
High Strength and Wear Resistance
The addition of manganese significantly improves the alloy's hardness and wear resistance. This means that during high-frequency magnetic latching switch operations, the Electric Current Measure Manganin Shunt can resist minor mechanical shocks and friction, maintaining long-term structural integrity.
Corrosion and Oxidation Resistance
The oxide film formed on the surface of manganese copper in air is stable and dense, effectively preventing further corrosion and ensuring long-term reliability of the Micro Ohm Manganin Welding Shunt Resistor in humid or highly corrosive environments.
Core Advantages of Electron Beam Welding
Deep Penetration and Narrow Heat-Affected Zone
The electron beam has extremely high energy density, achieving complete fusion with a penetration depth of 1.0-2.0 mm. This results in a large weld width-to-depth ratio and a heat-affected zone width of less than 0.5 mm. This minimizes performance degradation caused by heat input, particularly protecting the temperature-sensitive electrical properties of the manganese-copper layer for Magnetic Shunt Customized.
Pure Weld and High Strength
Welding in a high-vacuum environment effectively prevents oxidation of active metals such as copper and manganese. The weld zone has extremely low impurity content, and the bonding strength can reach over 95% of the base material strength, ensuring no interlayer delamination occurs under subsequent stamping and long-term current impact for Micro Ohm Manganin Welding Shunt Resistor.
Precise fusion control
High-precision beam current and scanning control ensure the uniformity of the manganese-copper layer thickness across the entire width of the composite strip. This is crucial for ensuring consistent sampling resistance in batch Electric Current Measure Manganin Shunt.
Customized Services
We support full-dimensional customization services. Based on the customer's Manganin Shunt Resistor drawings and samples, we can flexibly customize the terminal structure dimensions, manganese bronze/copper strip thickness, resistance parameters, output voltage, lead type (quick-connect, pin-type), surface treatment (passivation, tin plating, silver plating), installation method, etc., to accurately adapt to the customer's assembly and scenario requirements for the magnetic latching relay. We provide free sample verification before mass production to ensure that the Electric Current Measure Manganin Shunt sample's welding quality, resistance accuracy, size specifications, and assembly compatibility meet the customer's design requirements before starting mass production, thus mitigating procurement risks. We also provide DFM analysis and process optimization to help customers optimize the terminal and magnetic latching relay compatibility design and reduce costs.
