Petracarbon offers a wide range of spring contact probes to meet your testing requirements and has been long recognized as the leading distributor for spring contact probes in the region. Utilizing a process that machines the barrel top into four bifurcated beams of precise length and profile, the design process stipulates that the beams are then coined to perfect center. This provides a compliant pressure fit against the plunger, resulting in a zero working clearance between the plunger and barrel. This technology is exceedingly effective at providing substantial performance gains. As compared to other spring contact probe designs in the market, namely single and highly variable contact points in bias designs, the bifurcated beams provide full radial contact to the plunger. This enlarged contact area never changes as the probe is compressed, always occurring at the point the plunger meets the barrel beams which results in the lowest, most consistent resistance of any probe.
