Universal Contacts PCB Contact System

Application / Market:

The Universal Contact series is an independent SMT contact that provides an electrical connection between a device and a PCB. Available in multiple heights (1.3-4.6mm), footprints, and configurations, UC is formed from a single piece of stamped material, and its domed contact point design delivers an outstanding Hertzian Stress performance level of a minimum of 0.3N of force and 300 psi with 0.1 mm of deflection. It is available in both beryllium and titanium copper alloys with nickel plate and gold plate over nickel in contact areas.


  • RoHS and REACH compliant
  • Up to 3000 mating cycles, dependent on application
  • Minimal X-Y-Z movement delivers excellent shock and vibration resistance
  • Domed contact point allows good hertz stress and low contact resistance
  • "Side wings" protect the active parts of the contact which prevent contact from overstressing and potential damage and provides the pre-load forces
  • Custom, preassembled plates allow rapid manufacturing / assembly intergration
