HarcoSemco’s Air Flow Sensors include high-stability platinum RTDs, precision heaters, and electronic interfaces. They provide analog DC voltage outputs and are adaptable to various installations, operating on the "thermal dispersion" principle for low flow detection in avionics cooling systems.
HarcoSemco’s Accelerometer Harnesses use low-noise cables with abrasion-resistant Nomex jackets. Designed for harsh environments, these harnesses provide a reliable, low-noise interface for accelerometers, featuring mil-spec connectors and superior EMI protection through advanced shielding.
HarcoSemco’s Landing Gear Harnesses are engineered to withstand extreme environments, including high g-forces, debris, and temperature variations during thousands of flex cycles. Constructed with impact-resistant rigid conduits and high-flex wires for reliable performance.
Custom-designed for specific aircraft models, HarcoSemco’s Flight Control Harnesses are built for resistance to SWAMP environments and temperature extremes. Featuring flexible conductors with nickel-coated copper braids, these harnesses include advanced termination techniques and epoxy encapsulation for durability.
The CFM56-7B Engine Harness by HarcoSemco is tailored to address in-service failure mechanisms and prevent false EGT readings, leveraging an FAA-approved Supplemental Type Certificate. This harness boasts improved component materials and construction for enhanced reliability and long service life.
HarcoSemco’s Engine Harness and FADEC are crafted to endure intense vibration and exposure to hazardous fluids in engine environments. Built with high-temperature materials, these harnesses ensure maximum reliability in critical on-engine applications.
HarcoSemco’s Fuel Cables are designed for installation within aircraft fuel tanks and provide sealing against fuel intrusion, qualified for pressures up to 50 PSIG. These flexible conduits enhance durability and prevent fluid ingress.
The APU Cable Harness by HarcoSemco features an open-bundle construction for ease of maintenance. This design reduces external coverings, ensuring straightforward inspection and repair in less critical environmental zones.
Designed for helicopter blade de-icing systems, HarcoSemco’s Blade De-Ice Harnesses withstand extreme rotational stresses, high-frequency movement, and temperature variations. These harnesses are validated through in-house endurance testing.
HarcoSemco’s Weapon Harnesses are engineered to handle demanding environments. Constructed with resilient materials and overmolded connectors, these harnesses provide superior protection against chafing, moisture, and vibration.
Proximity sensors work in a similar manner to variable reluctance speed sensors, coming in either hall effect or inductive sensing types. They respond to the presence or absence of a ferrous or non-ferrous target material within or outside a range of distances, providing an electrical output signal to indicate the target location. The housings are typically made of corrosion-resistant stainless steel, with customizable lightweight options available. The envelope and construction can be tailored for various applications.
