3M™ Twisted Pair Flat Cable
.050" 28 AWG Stranded, Mass Terminable, Halogen Free PO HF100 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 wire on .050 inch centers permits mass
     termination to broad line of IDC connectors
• See the Regulatory Information Appendix (RIA) in
     the “RoHS compliance” section of
    www.3Mconnector.com for compliance information
    (RIA E1 & C1 apply)

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 1500 ppm 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
