Amphenol

Amphenol Corporation is a global interconnect and sensor manufacturer headquartered in Wallingford, Connecticut. Founded in 1932 as the American Phenolic Corporation, the business grew from early radio sockets into one of the world's largest suppliers of connectors, antennas and sensor technologies, serving markets from industrial electronics to aerospace and data infrastructure.

The company's product portfolio includes high-speed, power, fibre-optic, harsh-environment and RF connectors; cable assemblies and harnesses; coaxial, power and specialty cable; antennas; pressure, temperature, position, vibration, gas and moisture sensors; busbars and power-distribution hardware; and a range of flexible and rigid printed-circuit solutions. Amphenol operates through numerous specialised businesses, which gives it unusually deep coverage of application-specific interconnect requirements.

For engineers, Amphenol is especially relevant when reliability, bandwidth, environmental sealing, power density or mechanical ruggedness are central to the design. Its product families cover everything from compact board-level connectors to aerospace circular interconnects and high-speed data-centre cabling, making the brand common across both mainstream electronics and highly specialised systems.
