Title:
多回転コードシャフトエンコーダ
Document Type and Number:
Japanese Patent JP2004515758
Kind Code:
A
Abstract:
In a multiturn rotary encoder, a first code disk is arranged with an input shaft for detecting the angular position of the input shaft within one rotation. To detect the number of rotations of the input shaft, a multiturn part is provided with further code disks in the form of magnet bodies which are driven geared down. A printed circuit board having detector devices for scanning the first code disk and the magnet bodies is positioned between the first code disk and the multiturn part. The detector devices of the first code disk and of the magnet bodies are mounted on one common side of a printed circuit board which is opposite the first code disk.
