Problem: To provide power to the welding arm of a robotic welding device, the manufacturer
needed a 50 ohm coax able to survive the continuous movement of the robotics arm. The cable needed to be flexible and rugged, with a long flex-life, in order to withstand the flexure and maintain signal integrity.
Because the cable had to interconnect the welding tip with the power supply, overall diameter was also a consideration.Solution: Knowing the strenuous demands of the application, Bay
Associates' engineers used a core of Kevlar® strands to serve as a strength member. A rugged silicone rubber compound was extruded over the fibers then wrapped with the first fine-gauge braid. A low
dielectric polytetrafluoroethylene (PTFE) tape was used to ensure low loss, small size, and flexibility. The stringent electrical requirements were met with the application of a second fine-gauge alloy shield over
the dielectric. For ruggedness, durability, and flexibility, a neoprene overall jacket was selected. |

Problem: A robotics component retrieval application called for a flexible 103-conductor cable to be
guided along in a festooning track without wandering. The cable needed to be designed in such a way that it fit properly in the perimeters of the track, wouldn't
slip, and could withstand the flexing rotation of the track without compromising the cable's electrical characteristics.Solution: Bundling the 103 conductors into three individually shielded
hybrid cables, Bay's engineers then parallel extruded the three into a single flat cable meeting the width of the cable track. Using a fluoropolymer insulation for smaller size and thin wall construction, Bay
was able to keep the overall height of the cable low. A unique jacketing material increased ruggedness and flexibility, greatly improving overall cable life. |
