ACES Connectors offers a line of FAKRA connectors designed for use in high-frequency automotive applications, including GPS and camera systems. The line is currently comprised of straight male and female cable-mount connectors and a right-angle male board-mount connector, all three of which are mating compatible with other FAKRA connectors on the market and are rated for 1A and <36VAC per pin. The three FAKRA connectors are also rated for a maximum of 40mΩ contact resistance, a minimum of 800VAC dielectric withstanding voltage, and a minimum of 100MΩ insulation resistance, and are best suited for in-vehicle rather than externally mounted applications since they don’t offer sealing.  

Materion’s Alloy 174 (UNS C17410) mill-hardened copper beryllium (CuBe) alloy strip material provides design flexibility, ease of manufacturing, high-reliability, and durability in miniaturized, high-density, and high-temperature automotive, aerospace, datacom, telecom, medical, and consumer electronics applications including connectors, terminals, and spring contacts for switches and relays. Designed to fill the performance and cost differential between lower performance copper alloys, such as brass, and higher performance beryllium copper alloys, Alloy 174 is engineered to carry high current with a low temperature rise and exhibits superior resistance to stress relaxation at high temperatures, an impressive formability to strength ratio, high electrical conductivity that is four times greater than bronzes and twice that of brass, thermal conductivity that is three to five times greater than competitive copper alloys, enhanced reliability, and predictable normal forces. It ruggedly withstands high stress with a yield strength of up to 125ksi — which is superior to traditional strip alloys including phosphor bronze, silicon bronze, aluminum, brass, and copper nickel alloys — exhibits long-term thermal stability, maintains the highest spring force of any traditional copper alloy at temperatures in excess of 200°C (even when miniaturized), is easily formed into complex shapes, improves signal transfer, enables low insertion and withdrawal forces, and is well suited to highly repetitive cycle lives. When stressed to 45ksi (310N/mm2) in severe reverse bending mode, Alloy 174 still delivers a cycle life of more than 100 million operations. Standard Alloy 174 material features a stain-inhibiting treatment on the surface, which provides temporary protection against the growth of surface films like oxides in even industrial environments with 90% relative humidity at 32.22°C, and is also available with tin plating, solder coating, and precious metal inlays. It is compliant with ASTM B 768, ASTM B 888, and UNS C17410 standards for easier integration with existing projects and specifications.
