MicroE Systems’ new O.P.S.™ (Optical Positioning Sensor) optical encoder series sets the new standard for performance and value, in precision and speed of motion systems and metrology equipment. Its combination of resolution up to 50nm, fast-installing tape scale, dual optical limits, and status LED in the sensor make it the encoder of choice for OEM applications in CMM’s, semiconductor equipment, linear stages, medical robots and scanners, microscope stages, and many more.

O.P.S. encoders have low cyclical error, just ±40nm, enabling improved 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.

Continuing MicroE’s strategy of putting all electronics in the sensor, O.P.S. is our first product with a built in setup and status LED. The tri-state LED shows signal strength in real time, reassuring you that the encoder is working correctly during system operation. All electronics are in the sensor, which allows for easy configuration and customization of connectors and an overall small system design.

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 built-in optical index and limit marks that are within the 6mm width of the scale, making it the most compact tape scale available. Combine this with O.P.S.’s dual optical limits, class-leading wide alignment tolerances, and a compact sensor only 8.9mm high, and O.P.S. encoders make a strong presence as both convenient and flexible.

Compared to competing products, O.P.S. encoders offer superior performance in a smaller package with a significantly lower cost per unit.
