What Is the Temperature Rating for NI SHC68-H1X38 Cable (Part Number 192681‑1R5)?

Issue Details

This article provides information about the temperature specifications for the NI SHC68-H1X38 cable (Part Number 192681‑1R5), a shielded, 50 Ω single-ended flying-lead digital cable. While NI does not publish a temperature rating for the entire cable assembly, component-level specifications are available.

Solution

Cable Description

• Part Number: 192681‑1R5
• Model: NI SHC68-H1X38
• Type: Shielded, 50 Ω single-ended flying-lead digital cable

Component-Level Specifications

Although the cable assembly does not have an official temperature rating, the following components provide relevant information:

Wire Specification

• Part Number: 763629-01
• Description: WIRE, 26 AWG, high strand count, black insulation
• Temperature Range: -65 °C to +200 °C

Sleeving Specification

• Part Number: 746516-01
• Description: Flame-resistant nylon sleeving, 3/16" diameter
• Temperature Range: -50 °C to +125 °C

Note: These ratings apply to individual components and do not necessarily represent the entire cable assembly. NI does not perform extreme environmental tests on cables or accessories unless explicitly stated in the documentation.

Additional Information

Recommended Practice: 

• Assume the working temperature of the cable or accessory is the same as the product it is designed to work with, since testing is conducted under those conditions.
• Consider the temperature gradient stress that the cable may experience. Ideally, use fixtures to separate normal and operational (hot/cold) areas for proper thermal isolation.
