Spring Probe Contact Technology

Smiths Interconnect is the world leader in spring probe contact technology.  Constructed of a barrel, spring and plunger, spring probes are used extensively in PCB board test applications as well as a contact technology embedded in compliant board to board interposers and connectors.

Features

  • High compliance to length ratio
  • Low provide design is forgiving of challenging mating conditions and heavy vibration
  • Short signal path ensures high signal integrity for analog and digital applications
  • Internal biasing techniques provide stable contact resistance even under heavy shock and vibration
  • Long cycle life ranging from 20K - 300K cycles depending on design and application
  • Variety of contact termination styles including flexible or rigid PCBs, through-hole, surface mount or compression mount
  • Ideal for blind mate applications and can engage at 90° angle to the target
  • Great approach to quick disconnect applications
  • Require only a flat pad as mating target
  • Exceptional target misalignment tolerance; can accommodate x, y, z, angular and rotational variances in target placement

Applications

  • Used in a variety of Defense, Aerospace, Space and Medical Applications
  • Ground and air-based radar, satellites, missiles, fixed wing and rotary aircraft, test & measurement environments
  • PCB Interposers
  • Blind-Mate Connectors
  • High Density Connectors
  • Compliant Connectors
  • PCB Board Test
  • ATE Interface
