Smiths Interconnect S-0, S-3, and S-5 Series

Standard Board Test Spring Probes

Smiths Interconnect offers a wide range of spring contact probes to meet your testing requirements, and has long been recognized as the world's largest probe manufacturer. With over 60 different probe series that include the standard board test fixture probes, as well as specialty test probes, IDI provides a full portfolio designed for general-purpose test on bare boards, loaded printed circuit boards, surface mount assemblies, and other forms of test.

IDI probe designs feature a bifurcated barrel with four separate fingers. The barrel is compliant and formed against the plunger, thus eliminating any gap between the plunger and barrel. ICT probes are more accurate and stable in resistance than standard designs.
