BENEFITS
FEATURES
Smiths Connectors’ new Dovetail Connector Series features C Series Probes, renowned
for their incomparable shock and vibration performance, housed in a patent pending
block design. The symmetrical blocks interlock to allow for simple configuration into any
imaginable X-Y pattern. A multitude of probe options permit the benefits of a custom
connector design such as intermixing of power and ground functions within the same
array. Available for immediate delivery with no tooling required, the Dovetail Connector
eliminates the time and expense associated with typical prototype and low to medium
volume manufacturing activities.

SHOCK & VIBRATION TESTING
Smiths Connectors’ advanced C Series Probes offer exceptional compliance and design
flexibility in a wide range of applications. To enhance the capability of the series in military
applications, a version was developed which uses a bias ball design to guarantee
electrical performance especially in terms of vibration and shock.
Thorough shock and vibration testing revealed that the C Series Probes passed
vibrations tests >15G and shock tests >50G regardless of the internal biasing technology.
During the resonance frequencies testing, the 15G input resulted in levels up to 120G
(Radial direction) and 60G (Axial direction) at the interface between PCB and spring
probe plunger.
After more than 10 hours of vibration and shock testing, the contact surfaces of the spring
probe tip and PCB are still free of any wearing or fretting corrosion with near perfect
surface finish.
