Product Insights

The header and receptacle-based wire-to-board connector segment represents a major product category because these configurations offer flexibility, serviceability, and reliable electrical contact between discrete wires and PCBs. Depending on the application, manufacturers can select vertical or right-angle configurations, single- or dual-row designs, different circuit counts, and various pitch sizes. TE Connectivity's portfolio illustrates the breadth of the product landscape, including headers, receptacles, PCB terminals, housings, jumpers, shunts, FFC/FPC connectors, and connector assemblies.

Traditional 2.54 mm and similar standard-pitch connectors continue to serve cost-sensitive and general-purpose applications, while smaller 1.0 mm, 1.25 mm, 1.5 mm, and 2.0 mm solutions are gaining importance in compact electronics. The trend toward smaller pitch is particularly visible in automotive electronics, wearables, portable devices, industrial controllers, and connected appliances.

Power-oriented wire-to-board connectors are another important product category. As electronic systems require more power within smaller footprints, manufacturers are developing connectors that combine compact packaging with higher current capacity. TE Connectivity's Economy Power and Economy Power II products, for example, support applications requiring higher current in compact PCB architectures, including appliances, industrial machinery, and lighting.
