Rotary encoders are electro-mechanical devices used to monitor and control the position and angular speed of rotating shafts. In particular, incremental encoders track positional changes relative to a defined reference point. As a result, they operate independently of the direction of rotation. By generating electrical pulses, they measure rotation, speed, and acceleration. However, the reference (zero) position must be reset at each system start-up.

Overall, our magnetic incremental encoder range offers durability, compact design, and reliable performance across demanding industrial environments.
