3M™ Round Conductor Flat Cable
1 mm 28 AWG Stranded, Halogen Free PO HF625 Series
• Low Smoke Zero Halogen (LSZH). Insulation Advantages of
     LSZH insulation are the low smoke (IEC 61034-2:2005), and low
     toxicity of combustion gases (NF X 70-100-2:2006), reducing the
     risk to firefighters, and reducing the soot and corrosion damage to
    nearby equipment
• Broad operating temperature range from -40°C to 105°C
• 28 AWG stranded conductors on 1mm pitch permits mass
    terminations to a broad line of metric IDC connectors
• Zippable for branching or discrete terminations
• See the Regulatory Information Appendix (RIA) in the “RoHS
      compliance” section of www.3Mconnector.com for compliance

UL File No.: E42769, Style No.: 21682 Halogen Free is defined as both 1) no halogen compounds that are intentionally added to the product or
used in the manufacturing process for the product and 2) any impurities present are less than 900 ppm
bromine, less than 900 ppm chlorine and/or less than 1500ppm total bromine and chlorine. The latter
are the levels set forth in certain industry standards for printed circuit boards, such as the International
Electrotechnical Commission (IEC) 61249-2-21 standard. This information represents 3M's knowledge
