HARWIN 1.28 mm Spring Contact Titanium Copper Alloy Surface Mount Gold Plating S7231-45R

HARWIN S7231-45R 1.28 mm Spring Contact is a precision surface mount component made of titanium copper alloy with gold plating. It offers an ultra low profile design ideal for antenna feed applications in mobile devices such as smartphones. The spring contact includes engineering features like a protected tip to prevent hooking and a positive stop shoulder to avoid overcompression, maintaining reliable spring force over time.

This spring contact supports a current of 1 ampere and has a low contact resistance of 50 milliohms, ensuring efficient conductive performance. Its compact form factor with dimensions of 1.28 mm height, 2.5 mm length, and 1 mm width enables integration into small electronic assemblies requiring reliable grounding or contact points.

These spring contacts are designed for both wiping and sliding motion contacts, suitable for automated placement processes using standard SMT equipment, boosting production efficiency.

Common applications include antenna feeds in mobile devices, RFID tag connections, and LED lamp contacts. Manufactured in Korea, they comply with industry standards for electronic components.

Constructed from titanium copper alloy for durability and conductivity. Gold plating provides excellent corrosion resistance and low contact resistance. Positive stop shoulder protects against overcompression and permanent deformation.

Protected tip design minimizes the risk of hooking during assembly. Suited for wiping and sliding action in electronic applications. Compatible with standard SMT automated assembly machines. Manufactured under strict quality controls in Korea.

These HARWIN spring contacts are ideal for use in industrial electronic manufacturing, telecommunications, and other precision assembly sectors.
