Motion feedback encoder.
The Mercury 1800 (M1800) digital kit encoder provides 50-nanometer
resolution from the sensor and measures 8.9 mm tall. The encoder is
available in two resolutions: 50 or 100 nanometers, linear, or up to 6.5
million CPR rotary. All electronics are inside the sensor, making it
ideal for high-noise industrial applications. The encoder's high
resolution minimizes cogging for smooth motion control, while its 1-LSB
optical index, which is integrated into the scale, allows system
repeatability and ease of setup. With the encoder, a motion system can
achieve startup and recovery at full encoder resolution.
