FCT is a precision small grating measuring system suitable for precision measurement in small measuring ranges, especially for measuring, robotics, medical equipment, precision modern processing equipment. Usually used for continuous thickness measurement. FCT linear scale linear displacement changes into pulse signals.The number of pulse signals corresponding to the distance moved, the pulse frequency is a reaction speed. FCT The body consists of a set of precision linear plain bearings, return springs, glass gratings, LED lighting system components. FCT output signal is rectangular square wave. A, B phase 90 ° difference between the two-way waveform, can indicate the moving distance and direction.
FCT output signal (when moving to the inside of the scale)
            Standard (no zero signal)                               Optional (with zero signal)
