Products Description
Armature for Electromagnetic Relay is a key mechanical component in automotive electronic control systems. Its core function is to precisely transmit the magnetic field generated by the electromagnetic coil to the armature, thereby driving the relay's on/off action. This product utilizes a 3-5 micrometer (µm) copper plating treatment on the armature surface, ensuring high magnetic permeability while effectively reducing contact resistance and improving corrosion resistance and service life.
Copper Plating
Low Resistance
Copper's electrical conductivity is second only to silver. The copper plating layer significantly reduces the contact resistance between the Relay Armature and the contacts, ensuring reliability under high current conditions.
Corrosion Resistance
The copper layer effectively prevents the Relay Terminal Armature substrate (usually an easily oxidized iron alloy) from rusting in humid environments, making it particularly suitable for complex environments like automotive engine compartments.
Abrasion Resistance
The copper plating layer for Relay Armature Plate Terminal exhibits good abrasion resistance during mechanical movement, extending the relay's lifespan.
Design Advantages
Magnetoelectric Synergistic Structure Design
Utilizing an integrated design of "magnetic substrate + 3-5μm precision copper plating + assembly positioning platform," it balances magnetic and electrical conductivity, solving the pain points of traditional Electrician Pure Iron Armature. This results in rapid and stable relay engagement, with a response time reduced by more than 15% compared to traditional methods.
Vehicle-Grade Vibration-Resistant Positioning Design
The assembly end features dual positioning pins and anti-foolproof slots, achieving a positioning accuracy of ±0.01mm. This allows for seamless adaptation to the relay coil frame and core, resisting severe vehicle vibrations and preventing relay malfunctions caused by Relay Armature Plate Terminal displacement, thus ensuring system stability.
Wide-Temperature Adaptability Structure Optimization
The arc-shaped transition design eliminates stress concentration, allowing for deformation and cracking within a wide temperature range of -40℃ to 125℃. This adapts to different regional operating conditions, prevents copper plating for Relay Terminal Armature peeling and substrate oxidation, and extends service life.
