The T20 sockets, moulded from DuPont™ Zytel® HTN PPA (polyphthalamide) withstand higher temperatures than the S8 sockets used in most North American cars. Empire moulds the new 2.8 In-Line connector series from hydrolysis-resistant DuPont™ Crastin® PBT thermoplastic polyester resin.

T20 sockets predominate in European and Japanese vehicles but are now gaining broader use in North America. Empire’s T20s deliver the same power output as S8 sockets but are more compact. Their reduced footprint and smaller socket hole opening give automotive lighting designers more styling freedom and a larger potential reflecting area, but they result in higher operating temperatures.
“Zytel® HTN PPA allows us to meet our customers’ stringent temperature requirements for T20s while giving us several pluses over alternatives such as modified polyphenylene oxide,” said Robert Gray, Empire’s director of program management. “Key advantages for the PPA material we selected are very low outgassing, good moulding productivity and the excellent technical support provided by DuPont.” The material’s low outgassing greatly reduces film formation on lighting lenses, which reduces light output over time.
The sockets in Zytel® HTN PPA consist of two moulded parts assembled by the cost-effective ultrasonic welding process. Each part can be colour-coded as an identification aid in wire harness assembly and installation.
DuPont™ Zytel® HTN high-performance polyamide resins are engineered for extremes for demanding environments. The portfolio includes both Zytel® HTN PPA grades for heat, chemical and moisture resistance and Zytel® HTN structural grades. Empire uses a toughened, glass-reinforced grade of Zytel® HTN PPA that can use water for mould temperature control. “We like water control because it avoids the added cost of oil-type control equipment and makes it easier to maintain a safe, clean moulding operation,” Gray said.
For its new 2.8 In-Line connector series, Empire selected a glass-reinforced grade of Crastin® with outstanding hydrolysis resistance. Gray explained the choice: “The Crastin® resin gives us a combination of hydrolysis resistance, dimensional stability, an excellent balance of strength and impact resistance, and high flow for easy moulding.” The connectors comply with demanding USCAR requirements for retention of terminal pullout resistance and other key functional characteristics after rigorous thermal cycling tests involving hot, cold, humid and dry conditions.
“DuPont gave us great service in our development of both sockets and connectors,” Gray said. DuPont specialists accelerated Empire’s development of marketable parts with expert input on material selection, design, tooling and ultrasonic welding. The DuPont Application Development Center in Troy, Michigan, conducted initial moulding trials.

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
