Technology Driven Innovators for Over 60 Years

At BEI PSSC, designing sensor systems to fit unique measurement requirements is what we do best. Thousands of BEI PSSC encoders, accelerometers, and motion control systems perform critical operations for a variety of space, military, scientific, and range/tracking applications each and every day. Our strength lies in our ability to match our motion-sensing technology with your application-specific requirement. Rugged by design, BEI PSSC encoder and accelerometer systems can be constructed of stainless steel, aluminum, titanium, beryllium and plastic composites.
