SM 50 is a precision small grating measurement system, which is suitable for small-scale precision measurement, especially for measurement, robots, medical equipment and precision modern processing equipment. It is usually used for continuous thickness measurement. SM 50 grating ruler converts linear displacement change into pulse signal. The number of pulse signals corresponds to the moving distance, and the pulse frequency reflects the moving speed. The main body of SM 50 consists of a set of precision linear ball bearings, return springs, glass gratings and LED lighting system.
The output signal of SM 50 is a rectangular square wave, and the phase difference between A and B is 90, which can indicate the moving distance and direction. Z-phase waveform is a zero pulse signal, which is generally located in the middle of the measured length. The output signal can be linear differential or TTL square wave as required.
