Harwin Spring Contact Surface Mount, 2 mm Height, Titanium Copper Alloy, Gold Plating S7271-45R

Harwin S7271-45R Spring Contact is an ultra-low profile grounding contact engineered for modern PCB assemblies, particularly in mobile devices and other compact electronics. With a surface mount configuration, this spring contact is manufactured using a titanium copper alloy which provides excellent durability and reliable electrical performance.

The gold plated contact ensures optimal conductivity and enhanced corrosion resistance, vital for robust connections in harsh environments. The component’s compact dimensions, including a height of 2 mm, length of 3.5 mm, and width of 1.5 mm, make it compatible with space-constrained designs.

Capable of handling currents up to 1A and featuring a low contact resistance of 50 mΩ, the device guarantees precise and efficient performance. Its design incorporates a positive stop shoulder to prevent overcompression, which safeguards the spring force and extends the component’s usable life. A protected tip avoids unwanted hooking and allows for wiping and sliding operations during device assembly or movement.

Harwin’s EZ-BoardWare series includes these spring contacts for antenna feeds, grounding, and signal integrity enhancement in assemblies such as smartphones, LED lamp connections, and RFID tags. The S7271-45R is optimized for automated placement processes, streamlining manufacturing workflows by compatibility with standard industry placement equipment.

Applications for the Harwin S7271-45R range from mobile device antenna feeds to PCB grounding points, LED lighting connections, and RFID systems in commercial, industrial, and laboratory electronics.
