3M HF539 Halogen-Free Flat Cables

3M Halogen-Free Flat Cables product line has been expanded to include HF539 Medium Flex Life Cable, Halogen-Free Cables. The HF539 Halogen-Free Flat Cables combine 3M’s proven medium flex life conductor with a low smoke zero halogen PO dielectric. The HF539 Series is rated up to 10 million flex cycles over a 1 3/4” bend radius. 3M Halogen-Free Flat Cables have Low Smoke Zero Halogen (LSZH) polyolefin insulation, resulting in low smoke (IEC 61034-2:2005), low toxicity of combustion gases (NFX70-100-2:2006), and reduced soot and corrosion damage to nearby equipment.
