55A0121-24-0/5

Overview

The TE Connectivity Aerospace, Defense and Marine part number 55A0121-24-0/5 is a single-conductor hook-up wire from the 55A series. It features a 24 AWG stranded conductor composed of 19 strands of 36 AWG wire. The conductor material is tinned copper, providing corrosion resistance. The insulation is made of radiation-crosslinked ethylene tetrafluoroethylene (ETFE), which offers high thermal stability and chemical resistance. The rated voltage for this cable is 600V. The operating temperature range extends from -65°C to +150°C. The insulation color is orange. This component is designed for use in demanding aerospace and defense environments requiring reliable electrical interconnects.

Feature Summary

• Radiation-crosslinked ETFE insulation provides high thermal endurance and chemical resistance
• Tinned copper stranded conductor ensures flexibility and corrosion protection
• Rated for 600V operation in harsh environmental conditions

Applications

• Military aircraft wiring systems
• Electronic warfare equipment interconnects
• Unmanned aerial vehicle (UAV) internal wiring

Procurement Notes

Verify the specific order suffix against the manufacturer's current datasheet to confirm insulation color and packaging format. Confirm that the radiation-crosslinked ETFE specification matches the design requirements for the target operating temperature range. Ensure compliance with relevant military standards such as MIL-W-22759 or equivalent specifications required by the system integrator before finalizing procurement.

Selection Notes

Select this component when a 24 AWG wire with high-temperature ETFE insulation is required. The tinned copper conductor is suitable for applications where solderability and corrosion resistance are critical. Verify that the 600V rating meets the circuit voltage requirements. Consider the -65°C to +150°C operating range to ensure performance under expected thermal loads.
