About BEI Precision
BEI Precision traces its roots to 1862 when D.H. Baldwin founded the D.H. Baldwin Company in Cincinnati, Ohio, initially building pianos and later electronic organs. The optical encoder technology emerged from the development of "Tone Wheels" for organs, and the company now operates from Maumelle, Arkansas, where its manufacturing plant continues that legacy of precision. The company designs and manufactures high‑precision optical encoders — housed and un‑housed (kit) designs, absolute and incremental, single‑turn and multi‑turn — as well as flight‑worthy pivot‑and‑jewel accelerometers, displacement sensors, and rotary optical scanners. All products are designed and manufactured in the USA, available in both ITAR‑controlled and EAR‑regulated configurations, and supported by a broad engineering network and robust supply chain for custom and sole‑source solutions. BEI serves defense primes, aerospace OEMs, and government programs across air, land, sea, and space domains. Its encoders provide gimbal feedback for airborne ISR payloads, precision angular measurement for weapons targeting systems, and closed‑loop positioning in next‑generation combat vehicles. Accelerometers are deployed in fixed‑wing, rotary‑wing, and unmanned platforms for flight control and vibration monitoring, while optical scanners support EO/IR systems in ISR payloads, weapons sighting, and airborne surveillance. A long heritage of sole‑source programs with defense primes and ITAR‑compliant domestic production underpin its position in mission‑critical sensing.
