Frequently Asked Questions

What makes this cable "flexible"?

The 2090-CFBM7DF-CEAF01 uses fine-strand conductors and TPE jacket for high-flex applications.

Is this suitable for cable carriers?

Yes, it is specifically designed for cable carrier installations with >10 million flex cycles.

What is the voltage rating?

It has a 600V maximum operating voltage rating for industrial safety.

How does this differ from standard cables?

It has finer conductors, more flexible jacket, and higher flex life rating.

What is the minimum bend radius?

The dynamic minimum bend radius is 7.5 times the cable diameter.
