Kelvin Test Contactors (Sockets) / Probe Heads

Highest Performance at Best Cost of Test for Automotive and Industrial

The durable one piece design combined with the proven self-cleaning wipe and full Kelvin capability enable a low and stable contact resistance, a high current carrying capability and an extended temperature range. The Kelvin contactors are developed and optimized to reduce cost of test. This is the result of a boosted first pass yield, enhanced production reliability, improved OEE and extended maintenance intervals. Moreover testing at full specification values like high current and tri-temp with extreme temperature range are no longer a limitation.

High performance kelvin contact for high volume production test

cPython Kelvin contactors and probe heads provide superior electrical and thermal performance with significant cost savings. This makes cPython Kelvin ideal for lab and high-volume production test of analog and mixed signal integrated circuits – for applications such as power control, A-D and D-A converters, audio, video, power amplifiers, photonics, optical MEMS and sensors.

cPython Kelvin probes are electrically isolated and mechanically independent force and sense paths for true Kelvin contact for taking accurate measurements, even under high current conditions. These robust probes provide hundreds of thousands of insertions or touchdowns, and a bandwidth up to 26 GHz.  cPython Kelvin probes can land on 0.4 mm pitch targets, and their tip spacing is 90 µm to land on small targets. cPython probes are available with homogeneous tips to optimize performance.
