For power requirements, AeroPOWER® cables are engineered to provide reliable power to In-Flight Entertainment and Connectivity (IFEC) networks. The AeroPOWER® Firezone M25038/3 cables are built to withstand extreme temperatures in aircraft engine environments, rated to 260°C and offering 15 minutes of fire resistance at 2000°F.
The company also specializes in RF & Microwave Coaxial Cables, supplying QPL approved MIL-DTL-17 cables and advanced low-loss options such as the LL, SB, SS, and SFL Rock SStable® series, capable of operating up to 40 GHz. Additionally, Harbour produces Commercial & UL/CSA Cables, including M16878 Mil-Spec Hook-Up Wires and UL Appliance Wiring Material (AWM), along with Mil-Spec cables like M22759 wire and NEMA WC 27500 constructions, tailored for critical aerospace and military applications.
Technical Capabilities and Industry Presence
Harbour Industries' cables are engineered with proprietary fluoropolymer insulation, providing superior crush resistance, ease of termination, and tight bend radii. Their LL coaxial cables offer significantly lower attenuation, ranging from 20 to 35% below other MIL-spec cables of comparable size. The company serves a diverse customer base, including major aerospace and defense contractors like Boeing, Lockheed Martin, and Raytheon. Applications span In-Flight Entertainment, Cabin Management Systems, Ethernet Backbone Avionics, and critical systems in military aircraft (e.g., F-35, F-18) and ground vehicles. Harbour maintains rigorous certifications, including AS9100, and adheres to strict export compliance regulations such as EAR, ITAR, and OFAC, underscoring its commitment to quality, performance, and environmental responsibility through initiatives like its Green Initiative.
