Quantic BEI

Quantic BEI, known on its site as BEI, designs high precision optical encoders, accelerometers and motion control systems. Its markets are air, land, sea and space, with a focus on defense and aerospace. The site says the products are designed and manufactured in Maumelle, Arkansas. They are ITAR compliant for defense and government programs.

The encoder range includes housed and kit designs. It offers absolute and incremental encoders, and single-turn and multi-turn sensors. Product families include the GCC25, INC35, BIC35, LSI, MIL-157, MIL-257, MT40 and nanoSeries encoders. The site also lists accelerometers and 2-axis optical dither scanners.

The site says the encoders provide gimbal feedback for airborne surveillance and precision measurement for targeting systems. Accelerometers are used in fixed-wing aircraft, rotary-wing platforms and unmanned systems. The site says the accelerometers need no scheduled maintenance.

BEI says it has a long heritage of sole-source work with defense primes. It engineers products to a customer's interface, envelope and performance specs. Its products are built to handle wide temperature ranges, high shock, vibration, vacuum and radiation.

The site says the company's history starts in 1862 with the D.H. Baldwin Company of Cincinnati, Ohio, a piano maker. It also names Thistle Precision as a sister company.

The site has a request a quote form, an RMA request form and a contact form. It lists technical resources, supplier resources and career opportunities. The site lists no phone number. The company is on LinkedIn.
