The MWS M16878/4BEE9 is a single-conductor, 24 AWG hook-up wire engineered to MIL-W-16878/4 (Type E) specifications for high-temperature aerospace, military, and electronics applications. The wire features a stranded silver-plated copper conductor—19 strands of 36 AWG—insulated with extruded PTFE and rated for 600V operation across a -55°C to +200°C temperature range. Its 1.22 mm external diameter and medium-wall PTFE insulation provide excellent thermal stability and chemical resistance without external shielding.
