SMD-04B [Reflective Incremental Optical Encoder IC]
Maintaining the high resolution (A/B phase) of the conventional product SMD-01B, the origin detection function (Z phase) has been added, and the operating temperature range has been expanded.
The SMD-04B is a high-precision optical encoder IC that utilizes a diffraction image projection method. The SMD-04B integrates an OEIC (Opto-Electric Integrated Circuit) and an LED in a single package. It projects light emitted from the LED onto a scale and detects the relative movement between the SMD-04B and the scale by receiving the diffracted image of the reflected light with a photodiode. Additionally, by providing a pattern for origin detection on the scale, it outputs the Z phase, which is the origin signal. Furthermore, by arranging the photodiodes in an array at the receiving section, it minimizes the degradation of phase characteristics due to mounting accuracy.
