HARWIN 1.23 mm Ultra Low Profile SMT Spring Contact Titanium Copper Alloy Gold Plated S7221-45R

HARWIN S7221-45R spring contact is an ultra low profile SMT antenna spring contact tailored for high precision electronic components. It measures 1.23 mm in height, 2.6 mm in length, and 1 mm in width, crafted from titanium copper alloy with gold plating to ensure durable and reliable conductivity.

Designed for surface mount fixing method, this spring contact supports automated pick-and-place assembly processes commonly used in manufacturing mobile device antenna feeds, LED lamp connections, and RFID tags.

The contact resistance is rated at 50 milliohms, supporting currents up to 1 ampere, making it suitable for low power signal transfer applications. Its positive stop shoulder prevents over-compression, thus preserving the spring's mechanical properties and force consistency.

The protected tip design helps to prevent hooking during handling or operation, improving reliability in wiping and sliding applications. The ultra low profile and compact dimensions make it ideal for integration in confined spaces on printed circuit boards.

Constructed from titanium copper alloy providing robustness and excellent electrical conductivity. Gold plated contacts ensure corrosion resistance and high reliability. Surface mount fixing method facilitates efficient automated PCB integration.

Low contact resistance of 50 milliohms reduces signal loss effectively. Current rating of 1 ampere suits a variety of electronic component needs. Positive stop feature prevents over-compression and damage to the contact spring.

Protected tip helps avoid mechanical damage during application and usage. Designed for wiping and sliding actions common in antenna and sensor applications. Compact form factor enables integration into miniature electronic devices.

This HARWIN spring contact is suitable for industrial electronics manufacturing, laboratory prototype assembly, mobile device production, and other electronic component bonding applications requiring durable, low-profile spring contacts.
