MicroMo Electronics, Inc. introduces the world's smallest rotary encoder. The PA2-50 boasts an impressive 50 lines per revolution before quadrature utilizing optical technology packaged in a 6mm diameter housing. Operating at 2.7 to 3.3V DC with a battery-friendly current draw of 8mA, low-voltage battery applications continue running longer with more robust feedback signal reliability. (read more)

New line of absolute optical encoders world's first with 27-bit resolution at 36,000 rpm, 1 nanometer at 100 m/s.

Fine-pitch system delivers true absolute positioning in linear or rotary models. Unique single-track scale eliminates de-phasing from misalignment, allows wider setup tolerances.

Renishaw's new RESOLUTE™ optical encoder system is the world's first true absolute encoder cap... (read more)
