Interface transmits rotary encoder position data using fiber optics

Leine & Linde’s XHI 801 and XHI 803 rotary encoders, distributed through Heidenhain, are available with Optolink to transmit encoder position data using fiber optics. The transmitter provides secure data transmission in harsh industrial environments where electrical noise and long cable lengths can be problematic.

The transmitter technology permits signal transmission up to 4,921 ft. Because data is transmitted over optical fiber, the signal is not affected by electromagnetic disturbances, reducing the chance of measurement errors in electrically noisy environments.
