20 AWG ( 4 x 2 x 0,25 + 2 x 0,5) Helukabel 707739 TOPGEBER 512 PUR High Flexible Feedback Cable

20 AWG ( 4 x 2 x 0,25 + 2 x 0,5) Helukabel 707739 TOPGEBER 512 PUR High Flexible Feedback Cable

Applications:

These low-capacitance incremental encoder cables or position feedback cables transmit the control pulses for positioning and operating characteristics of servomotors. These cables are used as connecting cables for tachos, brakes and pulse generators in applications subjected to heavy mechanical stresses in industrial equipment, machine tools, control and automation equipment. Please observe applicable installation regulations for use in energy supply chains. EMC = Electromagnetic compatibillity To optimize the EMC features we recommend a large round contact of the copper braiding on both ends CE= The product is conformed with the EC Low-Voltage Directive 2006/95/EC.

●Core insulation of special polypropylene
● Core colours on demand
● Fleece wrapping facilitates sliding
● Overall screening of tinned copper wire braid with tinned drain wire, coverage approx. 85%
● Polyester foil
● Outer sheath of PUR
● Sheath colour green (RAL 6018) acc. to DESINA or orange

Properties:

●PUR outer sheath, low adhesion, extremely abrasion resistant, halogen-free, resistant to UV-, oil-, hydrolysis and microbial attack
● Special feature: These cables are produced to high quality specifications and conform to the DESINA®-standard
● Due to the high grade special core insulation, the PUR sheath and the highly flexible conductor, these cables are ideally suitable for use in drag chains and provide high functional reliability
● Optimum compliance with requirements for electromagnetic compatibility (EMC) by
approx. 85% coverage from the braided screen
● Particularly attractive for export-oriented
● The materials used in manufacture are cadmium-free and contain no silicone and free from substances harmful to the wetting properties of lacquers
● Resistant to cleaning and disinfecting agents acc. to ECOLAB
