The new Mercury™ 3500Si is the first high performance position feedback encoder to operate at maximum speed and maximum resolution. Utilizing the industry-standard SPI serial data interface, the Mercury™ 3500Si can achieve speeds of 7.2 meters/second, while operating at 5 nanometer resolution. The system is capable of speeds up to 50 times faster than standard
A-quad-B output encoders.

The SPI standard is supported by many DSP chip manufacturers including: TI, Motorola and Analog Devices. Encoder position values are digitized and sent directly into the controller's DSP. This format provides a robust connection that is ideal for encoder interfacing.

Like other Mercury™ encoders, the 3500Si is miniaturized. It has the smallest high-performance sensor head in the industry, just 8.4mm tall.

The Mercury 3500 also features LED indicators for instrument-free sensor alignment. Users can complete alignment procedures in under 30 seconds. Gain and phase correction are optimized automatically.

In addition to ultra high speed operation, the Mercury 3500's SmartPrecision™ electronics and SmartPrecision™ software provide robust programmable features. Users can program system resolution in binary steps from x4 to x4096 or 5 microns to 5 nanometers, linear and 6,600 to 67.1 million counts per revolution, rotary. Alarms for low signal alert are also programmable. SmartPrecision™ software even displays encoder data in several ways: a Lissajous data plot of raw and corrected signals, position vs. signal strength, and position vs. velocity.

The Mercury 3500Si is ruggedized for high noise environments and delivers best-in-class noise immunity. SmartPrecision electronics are housed in a metal enclosure as are sensor electronics. All cabling is double shielded.
