Using fiber-optic technology within the cable assembly, the MR121 ZapFree encoder cable replaces standard controller-to-sensor connections and reduces ground-loop and interference problems in motion ...
Encoders are widely used to help control machine position and speed. Typical encoder output, a series of quadrature signals, consists of two full square waves, offset by 90° in phase. The number of ...
It takes considerable time and effort to manufacture “perfect” surfaces. The mirrors on NASA’s James Webb Space Telescope, with a surface area of about 25 m 2 and finished to accuracies of 25 nm, took ...
