How flexible is the cable for repeated movement applications?
The conductors are stranded with seven strands per core, enhancing flexibility for applications requiring frequent bending.
What environmental temperature extremes can it tolerate?
It is specified to operate down to −40°C and up to 105°C, supporting cold storage and high‑temperature zones.
Is the cable suitable for screened or noise‑sensitive circuits?
The construction is unshielded, so additional screening or earthed trays are recommended for EMI‑sensitive installations.
How long is each reel and how does that affect procurement?
Each length is supplied as 100 ft, allowing planners to calculate runs and minimise jointing in assemblies.
