Accommodating all the electronics, including interpolation and accuracy enhancing circuitry, within the sensor, rather than in a separate unit, the MicroE Systems O.P.S. optical encoders from INMOCO can be fitted in a single step process and set up intuitively. They are suitable for OEMs and end user applications, particularly where space is restricted or customization is required. The optical encoder combines a digital output resolution up to 50nm, low cyclical error, fast-installing tape scale and dual optical limits along with the sensor's built-in status LED. These features will make it the encoder of choice for many users. OEM applications include CMM's, semiconductor equipment, linear stages, medical robots and scanners, microscope stages, while end users will appreciate the advanced precision they bring to virtually any application. Ensuring exact positioning and velocity control, the encoders have a cyclical error of just ±40nm. Similarly, resolution performance excels for precision motion applications: linear resolutions of 1µm, 0.5µm, 0.1µm and 50µm are available in the series, while rotary resolutions of 163k CPR to 3.3M CPR are offered. The encoder 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-mounted Tape Scale II is obtainable with built-in optical index and limit marks that are within the 6mm width of the scale, achieving one-step installation. The tape is cut-to-length, with built-in or stick-on optical index and limit markers, while the pitch is 20μm. Measuring lengths may be up to 30m. Rotary glass scales are available with or without hubs, and in arc segments. Aiding installation, alignment tolerances are ±2°, while built-in separate left and right optical limits also speed up fitting. The advanced optical design and automatic gain control reduce sensitivity to dust, fingerprints and other contamination on the scale. The encoders combine O.P.S.'s dual optical limits, class-leading wide alignment tolerances, built-in interpolation and a 8.9mm high compact sensor.
