Energy Harvesting Technology: Electronic multiturn encoders.

The absolute encoders Multiturn Sendix M3661 / M3681 with analog output and magnetic sensor technology are based on Energy Harvesting Technology and are equipped without gears or battery. This makes them particularly robust, durable and cost-efficient. With their high IP67 protection, these encoders provide reliable operation in the harshest environments. Their compact design of only 36 mm allows easy installation in confined spaces.
