Inmoco has extended its Mercury range of digital encoders from MicroE Systems with the introduction of the Mercury 1800 kit encoder, which provide up to 50 nanometre or 100 nanometre resolution directly from the sensor. Measuring just 8.9mm high and containing all signal processing and interpolation electronics, the Mercury 1800 is quick to install, and perfect for high-noise environments, since no remote electronics are required.
The high resolution provided by the M1800 minimises cogging for smooth motion control, while its exclusive 1-LSB optical index, allows unsurpassed system repeatability, ease of system set-up and start-up, and also recovery at full encoder resolution. Importantly, the Mercury encoder index is built into the scale and requires no installation. This compares favourably with competitive encoders that offer low-speed Hall sensor indexes, which are time-consuming to install, often have to be adjusted to work correctly, operate at limited speeds and can only be read from one direction.
Wide alignment tolerances mean that OEMs can set-up the M1800 in about 30 seconds using MicroE Systems SmartPrecision alignment tool. In addition, Optional SmartPrecision software provides a digital read out in engineering units and Lissajous data plots for other set-up and diagnostic functions.
Two connector options are available with the M1800: The model M1800S is fitted with a standard high-density D-sub connector and is completely EMI shielded. The M1800H is equipped with a high-density micro connector for use very tight spaces. Digital A-quad-B output is standard and is RS-422 compatible.
