SMD-04B [反射型インクリメンタル光エンコーダIC]

Product Description

Based on high-precision Encoder IC SMD-01B, Index signal (Z phase) is added and expand the operation temperature.

The SMD-04B is a high precision optical encoder IC that employs a diffraction image reflection method.
It implements an OEIC (Opto-Electric Integrated Circuit) and LED in a single package. Light emitted from the LED is projected onto a scale, and the reflected diffraction image detected by a photodiode detector is used to determine the relative movement between the SMD-04B and the scale. A Z-phase origin signal can also be output by establishing a pattern for origin detection on the scale. It also features a photodiode detector array to reduce degradation in phase characteristics due to variations in mounting accuracy.
