Solution
The NI SHC68‑H1X38 (Part Number 192681‑1R5) is a shielded, 50 Ω single‑ended flying‑lead digital cable used with NI high‑speed digital instruments such as the PXIe‑6570. NI does not publish a single temperature specification for the complete cable assembly.
However, temperature details for the individual components used in the cable are available.
1. Wire Component Specification
-
- Part Number: 763629‑01
- Description: 26 AWG, high‑strand‑count wire with black insulation
- Temperature Rating: –65 °C to +200 °C
2. Sleeving Component Specification
-
- Part Number: 746516‑01
- Description: Flame‑resistant nylon sleeving (3/16″ diameter)
- Temperature Rating: –50 °C to +125 °C
Important Note:
The ratings above apply to individual components only. They do not represent an official temperature rating for the full SHC68‑H1X38 cable assembly. The assembled cable may be limited by factors such as:
-
- adhesive/epoxy used in strain relief
- connector plastics
- interaction of components under prolonged thermal load
Because of this, NI does not guarantee a specific operating temperature range for the complete assembly.
