Typical connection for Cryogenic sensors such as the CY7 series. The connection points (A) are made close to the sensor in the case of 4-lead measurement, and near or at the instrumentation for a 2-lead measurement. Generally, the 4-lead connection is preferred.

Can you siggest suitable length extension part for PT-103 by which I can extend up to 2 metres?

Asked by: Sundar
Adding additional wire would make it a custom part so the best approach is to send an rfq to temp@omega.com to get pricing and availability.
