Harwin Inc

Harwin makes high-reliability connectors and cable assemblies for demanding uses and supports customers worldwide. Its markets include aviation, defence, space, UAVs, energy, industrial, medical, metering and electric vehicles.

For aviation, Harwin says its products serve everything from the smallest turboprop to the largest passenger planes. Its connector ranges are called HRi, BBi and EZi. It also supplies cable assemblies for must-not-fail uses. For UAVs, it offers connections for camera drones up to unmanned planes. For space, it points to reliability under severe vibration, shock and high temperatures.

Harwin is an EN 9100 and AS9100D certified manufacturer. The company says it focuses on quality, safety and technology. It keeps improving its quality systems and invests in advanced manufacturing and automation. It also invests in computer aided design and engineering facilities, and it replaces equipment on a five-year cycle.

The company dates back to 1952. It began as a turning facility and grew into a specialist in reliable, high-performance interconnects. One family has led the business through that time. Harwin says it keeps adding new products through its focus on customers, quality and steady investment in people, processes and systems.

KEC Limited has joined the Harwin Group. KEC is a UK designer and maker of rugged interconnect products. It serves aerospace, defence and high-end industrial customers. Its range includes EMC backshells, glands and panel fittings, which sit alongside Harwin's own connectors.

Harwin trains its workforce through an apprenticeship programme that leads to an internationally recognised engineering qualification. It sells through a network of distributors and gives customers global technical support. Its 2026 Distributor of the Year awards recognise strong results in every global region. The company also says it aims to limit its impact on the environment.
