While both M22759 and M27500 mil spec wires are designed to meet stringent military specifications, M22759 is a single conductor wire known for its excellent insulation properties, whereas M27500 is a multi-conductor cable that includes additional shielding and an outer jacket for enhanced protection in environments where EMI/RFI shielding and multiple conductors are required. Here are some other differences between the two models military spec wires.
M22759 mil spec wire is a single conductor wire with high-performance insulation, where M27500 is a multi-conductor cable made up of several M22759 wires with added shielding and an outer jacket.
Usually, M22759 is used for internal wiring in high-reliability systems such as aircraft and spacecraft. M27500 mil spec wire is commonly found where multiple conductors and EMI/RFI protection are needed, such as in complex avionics systems.
When it comes to shielding M22759 mil spec wire does not include an inherent shielding layer where M27500 includes a shielding layer to protect against EMI/RFI.
When we speak about environmental protection, M22759 relies on its robust insulation for environmental protection. M27500 mil spec wire has an additional outer jacket for enhanced protection against physical and environmental damage.
