Frequently Asked Questions

What is "continuous-flex" construction?

The 2090-CFBM7DF-CEAF02 uses special materials and design for >30 million flex cycles in constant motion.

How does this differ from standard flexible cables?

It has higher strand count, specialized PUR jacket, and is rated for constant motion rather than occasional flexing.

What applications require this cable type?

Industrial robots, CNC machines, automated assembly lines with constant motion.

What is the temperature range?

It operates from -30°C to +105°C for harsh industrial environments.

Is this oil-resistant?

Yes, it is resistant to industrial oils, coolants, and cleaning chemicals.
