O.P.S. Series Encoders

MicroE Systems’ O.P.S. series encoders advance the precision and speed of motion systems and metrology equipment by setting a new standard for performance and value. The combination of resolution up to 50nm, fast-to-install tape scale, dual optical limits and a status LED in the sensor make it the encoder of choice for OEM applications in CMMs, semiconductor equipment, linear stages, medical robots and scanners, microscope stages, and many more.

O.P.S. series encoders have a low cyclical error, just ±40nm, enabling better positioning precision and velocity control. With linear resolutions of 1µm, 0.5µm, 0.1µm and 50µm, and rotary resolutions of 163k CPR to 3.3M CPR, O.P.S. fits many different applications.

O.P.S. is compatible with PurePrecision™ Tape Scale II and rotary glass scales. The same sensor works in both applications, reducing inventory requirements for multiple-axis machines. The fast-installing adhesive-mount Tape Scale II is available with a built-in optical index and limit marks that are within the 6mm width of the scale, making it the most compact tape scale available Combined with O.P.S’s dual optical limits, wide alignment tolerances, and compact sensor (only 8.9mm high), they are both convenient and flexible.
