Smiths Connectors is now Smiths Interconnect


Smiths Connectors is the world leader in spring contact probe design, and the industry’s expert in applying probes as connector contacts. Embodied in Smiths Connectors product lines, probes are an enabling technology that can fundamentally change the capabilities of the products which incorporate them.


Excellent For Blind Mate

Smiths Connectors' probe connectors featuring spring contact probes are compliant on the surface of their mating half, rather than extending into it as with conventional pin and socket connectors. This grants them their unique blind-mate capabilities.

Our connectors may be designed to engage at a ninety degree angle to its target, wiping into position to clear contaminates. Conversely, our connector may be disengaged at that same or any angle, making probes the best approach to quick-disconnect applications.

Low Profile, High Complaince Ratio

Smiths Connectors advanced spring contact probe technology permits a very high compliance-to-length ratio. This allows us to make connectors as compact as 2 mm, while maintaining 0.5 mm of compliance – low profile connectors have never been so practical or forgiving of mating conditions or vibration.

High Frequency

This short signal path, combined with Smiths Connectors industry leading expertise, permits remarkable signal integrity for both analog and digital applications. Speeds of 12 Gb/S and bandwidths of 20 GHz can be achieved with simple plastic spring probe interposers, and coaxial arrays and contacts can be used to permit excellent isolation.

Low Stable Resistance

Through Smiths Connectors decades of probe design experience, our connectors feature several innovations for control of DC performance. Advanced biasing techniques provide excellent stability of contact resistance, even under conditions of heavy shock and vibration. Our connectors can be designed to withstand up to 30 Amps of charge current.

High Insertion Life

Connectors based on spring contact probes are capable of remarkable longevity. Our probes are driven by helical coil springs, which maintain a constant force of contact over millions of cycles. Smiths Connectors plating and materials expertise combined with this engineering, delivers contacts that exceed the highest customer specifications for insertion life.

Environmentally Sealed

Smiths Connectors application expertise and the durable nature of our contacts, permits us to design connectors with excellent performance in harsh environments. IP68 and Mil810 requirements can be accommodated without sacrificing performance.
