What RDI does

RDI USA is a privately held electronic components manufacturer and contract manufacturer founded in 1988 by Robert L. Diamond and Barry Miller, headquartered in Mount Kisco, NY with wholly-owned manufacturing operations in Shenzhen, China. The company serves OEM customers across multiple verticals including consumer electronics, medical devices, IoT, and industrial process control, offering a portfolio of 240+ standard electronic components organized into four categories — Audio (buzzers, headsets, microphones, speakers), Switches (lever, push button, rocker, slide, tactile, toggle), Interconnect (USB cables, connectors, jacks, plugs), and Power Supplies (GaN fast chargers, IoT power supplies, wireless coils, Yagi antennas).

RDI's technology stack spans U.S.-based electrical and mechanical engineering, in-house tooling, SMT and through-hole PCB assembly, injection molding, PCB design, firmware and software development, industrial design, and quality assurance, with manufacturing executed at its ISO-9001-2015 certified Shenzhen facility. Notable technical capabilities include proprietary GaN-based USB PD and Qualcomm QC 3.0 fast chargers (RDIq sub-brand), isolated AC/DC IoT power supplies with 110V-270V universal input, MEMS microphones with profiles as low as 0.95mm, and ruggedized IP67/IP68 rated audio jacks and USB connectors. The company holds ISO-13485-2016 medical device certification and FDA registration, enabling entry into regulated medical OEM supply.

RDI generates revenue through two primary streams: hardware sales of standard and custom electronic components (quote-based pricing via an online RFQ system, distributed through Arrow Electronics, DigiKey, America II Electronics, and 10+ regional distributors plus manufacturer representatives covering all major U.S. regions) and professional services for contract manufacturing (turnkey design-to-manufacturing, engineering, prototyping, and high-volume production). The company has grown from 149 to over 900 employees in four years, and is led by Co-Founder and President Barry Miller with Co-Founder Robert L. Diamond serving as Chairman Emeritus.
