C Series Probes

Smiths Interconnect / IDI C Series Probes ensure a reliable, rugged connection in harsh environments. Standard pins offered in custom configurations meet the exact footprint of the user's application. Ground, power, and signal options are available in 6mm and 4mm lengths. These probes are ideal for RF, high-speed, and mixed-signal connectors. Ground contacts mate first and break last to support hot swap applications. The design supports increased current carrying capacity. The C Series Connector Probes are offered in surface-mount, through-hole, and solder-cup termination options.
