The grating ruler is divided into open type and closed type: The open type is high-precision type. The output waveform is a sine wave and is mainly used for digital transformation of precision instruments. The highest resolution up to 0.1 μm; closed type is mainly used for ordinary machine tools, digital transformation of the instrument, the output waveform for the square wave. The open sensor is made up of a grating scale and a grating read head. The enclosed sensor consists of a grating scale, a grating reading head and a housing in three parts. According to the appearance of the classification of small ruler, standard ruler, large ruler three. The product models are GBC2-B30 (small), GBC2-B10 (standard), and GBC2-B20 (large). The largest scale can be up to 3000mm.
Second, characteristics
