3M™ Round Conductor Flat, LSHF Cable, HF447 Series is the world’s first ribbon cable to be independently certified by Underwriters' Labs (UL) as meeting the definition of a Low Smoke, Halogen-free cable*. It is intended for internal wiring applications where a crucial design consideration is reducing the risk associated with smoke and corrosive gases during a fire event. The cable has a temperature rating of -40 degrees to +90 degrees Celsius and a horizontal flammability rating per UL. It is constructed of 30 AWG solid wires within a polyolefin blend insulation on .025" (.0635mm) centerline. It is zippable for branching or discrete terminations. The solid copper conductor can be soldered to a printed circuit board for direct attach wire connections. The new HF447 Series also works with several popular half – or fine – pitch IDC connector platforms, including 451 Series, 820 Series and Mini Delta Ribbon (MDR) System from 3M.
