3M™ Round, Shielded/Jacketed, Flat Cable
.050" 28 AWG Stranded, Mass-Term, Halogen Free PO/PO HF659 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
• Round construction permits easier routing
• 28 AWG wire on .050 inch centers permits mass termination to
     broad line of IDC connectors
• Continuous split/bond repeat allows for mass termination of IDC
      connectors
• Dual shielding provides 35 db average shielding
• Primary cable is zippable for branching or discrete terminations
• 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 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 and belief which may be based in
