National Instruments GMCT20-GMCT20 Switch Cable

The National Instruments GMCT20-GMCT20 (Part Number: 781256-01) cable is a 1-meter switch cable for precise signal routing between instruments and devices under test. The GMCT20-GMCT20 cable features 20-pin GMCT female connectors on each end and is designed for direct compatibility with the NI PXI-2585 PXI Multiplexer Switch Module and the NI PXI-2586 PXI Relay Module to ensure seamless integration and reliable operation in test applications.

The maximum voltage supported is up to 300 V and supports CAT II safety, enabling high electrical safety and reliability in various environments. Up to 12 A can be handled per channel. Furthermore, two channels are capable of running simultaneously at this maximum current. The GMCT20-GMCT20 has been designed for use over the long term in demanding operational conditions with consistent signal integrity, utilizing high-quality Positronic connectors along with rugged construction.

The GMCT20-GMCT20 Cable is commonly used in automated test systems and makes the integration of the NI switch modules for such complicated applications in signal routing relatively easy. It would be very useful in such tasks as multiplexing signal paths and connecting various instruments to DUTs that carry out diagnostics, quality control, and functional testing. The GMCT20-GMCT20 provides easy setup with preconfigured 20-pin GMCT connectors and correct alignment to the pin assignments of the supported switch modules.

The physical weight of the GMCT20-GMCT20 cable is approximately 499 grams, or 17.6 ounces, which gives a good balance between portability and robustness. This cable will operate within temperatures of 0 °C to 55 °C and store from -20 °C to 70 °C, enabling GMCT20-GMCT20 to work in most environments. Besides, it can support relative humidity of 5-85% without condensation, which also expands its applicability and reliability for indoor usages.
