| Cable Construction & Specifications |
| |
DynaFlex® 300 Series cables offer an optional polyurethane jacket for excellent UV
resistance in outdoor installations or for low smoke, halogen free jacket requirements.
Silver plated aluminum center conductors are best suited for applications requiring up to
1,000 flexures.
