Notes:
'Cleanroom qualified\lashunshielded analogue type: MULTIFLEX 512-PUR
Use:
These shielded special drag chain cables also offer application possibilities where external high-frequency influences disrupt the pulse transmission and are used for permanently flexible loads in machine and tool construction, in robot technology and on permanently moving machine parts, for continuous use in multi-shift operation. With free movement without tensile stress and without forced movement control, it has proven itself convincingly in drag chain use. It is a highly flexible control cable developed according to the latest state of the art, with slippery PP core insulation and a cut-resistant and low-adhesion PUR outer jacket that guarantees optimum service life and very high cost-effectiveness. For applications that go beyond standard solutions (e.g. in composting plants or high-bay conveyor systems with extremely high travel speeds, etc.), we recommend that you use our specially developed questionnaire for energy supply systems. For further application parameters, see the selection table: Cables for energy supply chains in the 'Technical information' chapter. For use in energy supply chains, please observe the assembly instructions. EMC = Electromagnetic Compatibility To optimize the EMC properties, we recommend contacting the copper braid on both sides and over a large area.
Standard lengths: 500 m, 1000 m
