New Mercury 11 1900 Encoder Can Reduce System Size and Cost While Improving System Performance With High Signal Quality and Speed

Mercury II 1900 can reduce the size and cost of virtually any motion system; at the same time improving system performance in high speed, high resolution applications. The encoder sensor - offering analogue 1Vpp sin/cos and index pulse outputs - measures just 8.7mm high. The benefit of this reduced height is amplified when the Mercury II 1900 is used with a tape scale; the resulting system being 58(percent) shorter than competitive encoders. Consequently, the Mercury II 1900 is easier to integrate into OEM designs. Moreover, the reduced dimensions of the overall system also help to reduce the weight and cost of motion systems, by allowing the use of smaller motors and stages.

In addition to high performance, all electronics are integrated in the Mercury II 1900 sensor. Users benefit from high-fidelity analog output right from the sensor, including higher system reliability, smaller footprint and a variety of connector options – including customer specific connectors or no connector at all. The integrated, low-power design results in power consumption of only 48mA at 5V – the lowest in its class.

The Mercury II 1900 is also easier to install and align than any other analogue encoder. Using the Mercury’s patented PurePrecision(trade mark) optics, advanced SmartPrecision II(trade mark) electronics and LED alignment indicators, all that is required is for the user to position the sensor against a reference surface, tighten the screws and the process is complete. This is possible thanks to relaxed alignment tolerances, particularly in the Theta Z axis. Mercury II offers a (= to 2 degrees) “sweet spot” – that’s a 300(percent) improvement over the best competitive encoder.

Also optimising system set-up, the Mercury II’s PurePrecision laser tape scale is fast and easy to install; it provides excellent accuracy and takes less space than any encoder in its class. The laser tape mounts using a permanent pressure-sensitive adhesive; any thermal expansion of the substrate being accounted for by anchoring the ends of the tape scale using epoxy and end caps. It is supplied in a convenient dispenser, in lengths up to 30m, enabling it to be cut any required length – minimising inventory costs.

Designed to operate reliably and consistently in the toughest EMI environments, the Mercury II 1900 features include all differential outputs, and double- shielded cabling for superior EMI/RFI immunity. In addition, scale contamination resistance ensures dependable encoder operation even against fingerprints, oil, dust, and other forms of contamination.

Supporting Mercury II is SmartPrecision (trade mark) II, the most advanced software in the industry. Supplied as an option with Mercury II encoders, SmartPrecision II adds unique functionality. It enables fast encoder set-up, alarms and analysis using a variety of data plots. In addition, the ability to email screen captures of data plots enables users to get rapid diagnostic support from MicroE Systems, no matter where their equipment is located.
