For linear motors, these cables are also available with 0.5 mm3 signal cores. | | Cable structure « TOPSERV7" 121 - Bare copper, ultra-tine wire to DIN VDE 0295 cl. 6 and/or IEC 60228 cl.6 - TPE-E core insulation, halogen-free - Black power supply cores with imprint U1, V2.W3 and green-yellow earth core - Black control cores with white imprint 5-6 and 7-8 - Screening of the control cores in pairs wrapped with plastic aluminium foil, copper drain-wire tinned and tinned copper braid, approx coverage 85% - Control cores stranded in pairs and laid up in layers together with the power supply cores with optimal lay length and stabilising filler - Fleece wrapping facilitates sliding - Overall screening of tinned copper wire braid, coverage approx 85% - PUR outer sheath: low adhesion, extremely abrasion resistant halogen-free, resistant to UV-, oil-, hydrolysis and microbial attack - PUR sheath: self-extinguishing and flame retardant, tost method B acc. to DIN VDE 0472 part 804 and IEC 60332-1 - Sheath colour orange (RAL 2003) according to DESINA, * Acc. to IN DRAM AT Standard | | Application • TOPSERV"' 121 The combination of supply cores with the control cores for the braking function and the thermal protection in these cables is ideal. - Precision servomotors, as used today in many areas of highly-automated manufacturing processes, call for high-quality, reliable and long-lasting cables These requirements are met to a high degree by these cables.The cables have an additional overall screen to ensure EMC compatibility, i.a for protection against electromagnetic interference. Production is based on the specifications of established manufacturers of servo-drives and controls, as well as on various VDE, ULand CSA standards Applications include machine, plant and robot construction, automation, drive, control and production engineering. Optimum compliance with requirements for electromagnetic compatibility (EMC) by approx 85% coverage from the braided screen. * EMC = Electromagnetic compatibility Note: To optimise the EMC features we recommend a large round contact of the copper braiding on both ends important: Attractive for export-oriented mechanical and system engineering. | | |
