SAE AS22759 wire is a fluoropolymer–insulated, single-conductor wire offering excellent performance for a variety of military aerospace and commercial applications. It has high performance and reliability in severe wind and moisture prone (SWAMP) zones such as engine nacelles as well as areas requiring overload stability, low smoke emission and fire resistance, such as aircraft cabins.
M27500-20SD1T14 meets SAE AS22759/34 specifications with a cross-linked, modified ETFE insulation surrounding an aromatic polyamide braid that provides an EMI/RFI shielding and features a tin-plated, copper conductor with a temperature rating of 150°C — offering both flexibility and durability.
This M27500-22SD1T14 Tefzel wire (Alternate Part# 20SD1T14) has a single tin-plated 20 AWG conductor, modified ETFE insulation.
