Allied Wire and Cable is a leading supplier of the Military specification M81044 hook-up wire, renowned for its lightweight, high-temperature resilience, and versatility across a wide range of applications including civil and military avionics, vehicles, marine, and electronics. Originally a military specification, M81044 wire is now governed by the Society of Automotive Engineers under the SAE-AS81044 standard, ensuring its adaptability and reliability in demanding environments.
Overview of M81044 Hook-Up Wire
High-Temperature and Durable Construction
The M81044 wire features high-temperature plated copper conductors and is protected by a cross-linked polyalkene insulation and a thin jacket made from cross-linked polyvinylidene fluoride (PVDF). This construction provides the wire with exceptional chemical, ozone, and temperature resistance, suitable for harsh operational conditions.
Versatile and Reliable Wire Specifications
-
Conductors: Depending on the specific type, M81044 wires use stranded silver- or tin-plated copper conductors, with some variants utilizing silver-plated copper alloy conductors. This allows for a wide range of applications, from delicate electronic assemblies to robust outdoor uses.
-
Insulation: The wire's cross-linked polyalkene insulation offers minimal shrink-back when heated, excellent abrasion resistance, and is compatible with potting processes used in electronic assemblies.
-
Jacket: The PVDF jacket provides a high level of chemical corrosion resistance, flexibility, lightweight characteristics, and heat resistance.
Applications of M81044 Wire
Widespread Use in Critical Systems
M81044 wire is primarily utilized in wiring harnesses found in avionics, military vehicles, ships, aerospace applications, and missiles. It's chosen for these applications due to its:
-
High-temperature resistance: Capable of withstanding up to 150 degrees Celsius.
-
Low weight and compact dimensions: Ideal for applications where space and weight are critical considerations.
-
Resistance properties: Offers robust protection against chemicals, ultraviolet light, ozone, fungus, and radiation, enhancing its longevity and reliability in varied environments.
SAE AS81044 and Other Specifications
Standardization and Compliance
While the M81044 wire was originally a military specification, it now falls under the purview of the SAE AS81044 specification, ensuring it meets rigorous modern standards for both military and civilian applications.
Comparison with Similar Cables
-
M27500 wires: These often use the same basic M81044 specifications but may feature higher temperature ratings and additional wire braid shields.
-
Raychem Spec 44 wire: Many types of Spec 44 can directly replace M81044, although variations in conductor materials and temperature ratings may occur.
