The LIE5 Series of optical linear encoders from BEI Sensors & Systems Co., Encoder Systems Div. (Sylmar, CA) are reflective-read devices that work in conjunction with a steel measuring scale. The wear-resistant scale features etched graduation markings of a 20-micron pitch with optical accuracy, and custom scale options are available.

The encoder features an encoder read head that employs flip-chip-on-glass optics, which accounts for its small size. "It's small yet powerful," says Ramesh Pavasia, vice president and general manager of BEI Sensors & Systems Co.

The LIE5 Series can include built-in interpolation circuitry with resolutions as fine as 0.1 micron, and output frequency up to 36 MHz. It measures 34 x 13.2 x 12.4 mm, which means the encoder can fit into tight spaces, and can travel at faster traversing speeds, with accuracies to 1 micron/m. The encoder is also rugged, as it resists scratches and can't be broken, Pavasia adds.

Applications for the LIE5 Series include CMM, X-Y machines, pick-and-place machines, and automated fluid-dispensing machines. Multiple industry applications include machine tools, process control, robotics, instrumentation, and military trackballs.
