Delphi Corporation was spun off from General Motors on May 28, 1999, establishing its headquarters in Troy, Michigan, USA. It is a global leader in automotive electronics, components, and system integration, with core businesses covering advanced electrical/electronic architecture, connectors, wiring harnesses, sensors, power management, and infotainment systems. The company’s flagship connection systems division offers a broad portfolio of connectors, terminals, and sealing products, including well-known series such as Metri-Pack, GT, Weather-Pack, and Harsh Environment connectors. Its sensor product lines span pressure, temperature, position, speed, and fluid-level sensors, widely used in powertrain, chassis, and body applications. Delphi also delivers power distribution centers, electronic control units, and hybrid/electric vehicle systems, supporting the transition to electrified and autonomous driving. At its peak, Delphi was the world's largest manufacturer of automotive interconnection products, commanding a leading market share and serving virtually every major automaker worldwide. With 185,000 employees, 171 wholly owned manufacturing sites in 41 countries, and 33 technical centers, the company achieved sales of $28.7 billion in 2004, ranking 160th on the Fortune Global 500. After financial restructuring, the Delphi brand continues under Aptiv PLC, but its engineering legacy and connector portfolio remain standard in vehicle electrical architecture.
