Product Benefits: 

  • Mercury II’s encoder technology achieves the highest resolution and accuracy in its class, with low cyclical error, low jitter, smaller sensors, and lower power consumption.
  • Broadest Alignment Tolerances: With the broadest alignment tolerances in the industry, a full +/-2 degrees, Mercury II is the easiest and the fastest sensor to align and setup. You can align the Mercury II sensor in under 30 seconds.
  • Built-in or Stick-on Optical Index and Limits: Order tape or linear glass scales with built-in markers for fastest installation, or install stick-on index and limit markers anywhere on cut-to-length tape scales.
