Motorcoder
The Motorcoder is a linear encoder that uses the permanent magnets track of a linear motor instead of a scale. It is an absolute position linear encoder compatible with Mitsubishi and Panasonic servos. It can be controlled with a resolution of less than 1um and a repetition accuracy of 10um over 3m/sec, and there is no need for magnetic pole detection.

Gearcoder
The Gearcoder is a hollow shaft encoder for robots with a gear-type scale. You can freely design the number of scale teeth, outer diameter, and hollow diameter without any additional customizing. It can sense multi-turn absolute position for over 10 years using a battery. Up to 8 Gearcoders and controllers can communicate with one cable. The Gearcoder is an optimized sensor for application to collaborative or industrial robots. The maximum resolution is 24bit/rev, and BiSS output is possible. The Gearcoder can be used with a Mitsubishi or Panasonic servo.
