Encoders, Accelerometers, Optical Scanners, and Custom Space Instrumentation for Military, Space and Aviation Applications

BEI PSSC provides application-based motion control components and sub-system solutions for military, aviation, space, range tracking, and scientific programs. BEI PSSC has continuously manufactured optical encoders and custom space instrumentation for motion control systems for over 60 years.

We have participated in space flight and military programs from the very beginning of our history, and have an enviable reputation for quality and reliability in the most demanding applications. NO failures have ever occurred in a BEI PSSC space system instrument.

We have the talent and experience to design motion systems successfully for nearly any environment. Our position instruments and systems are in use all over the world in satellites, missiles, planes, helicopters, ships, land vehicles, telescope and tracking mounts, as well as high-end industrial applications. BEI PSSC’s quality system, manufacturing capability, ISO controls, in-house environmental testing, and tailored test plans are unequaled.

Recent technological advances include mixed-mode ASIC chips combining sensors with signal processing and intelligence. These “smart” sensors are one-tenth the size of those available just a few years ago, and some versions house complete microprocessors.

We recognize that our products are only as good as the quality and value they provide, therefore, our quality and manufacturing systems are being continuously improved to provide the best value to you, our customers. At BEI PSSC, we continue to grow through a dedication to quality, technology, innovation, and quick adaptation to changing market conditions.
