An incremental optical encoder IC optimized for embedded applications, achieving resolution and miniaturization beyond submicron levels.
The SMD-01B is a reflective incremental encoder IC that utilizes a diffraction image projection method. This product integrates a photodiode and an LED in a single package. It detects the relative movement between the SMD-01B and the scale by projecting light emitted from the LED onto the scale and receiving the diffracted image of the reflected light with the photodiode. Additionally, by arranging the photodiodes in an array, it minimizes the degradation of phase characteristics due to mounting accuracy.
