We classify linear and rotary encoders according to the type of movement.
インクリメンタルエンコーダとアブソリュートエンコーダの違いは、ストップウォッチと時計の違いに似ています。
分解能とは、エンコーダによって検出される、最も小さい動きを指します。エンコーダのタイプによって異なります。
精度とは、出力があるべき場所にどれくらい近いかという指標です。
繰り返し精度とは、同一の物理位置で複数回測定した測定値の最大誤差です。
出力タイプ、読取りタイプ、エンコーダのボディタイプなど、最適なエンコーダシステムを選定するための目安を解説しています。
SATI stands for Stand Alone Trimming Interface. This is a stand-alone device with calibration and zeroing functions which eliminate the need for a reference encoder and works with dedicated AM4096-based encoders. SATI interface improves the encoder accuracy to +/-0.2°.
HiLin is the best performance linear incremental magnetic encoder for use in harsh environments. The encoder system consists of a readhead and a scale. The readhead is available in incremental output format. There are three different scale options available and each of them has its advantages compared to the other.
For Nonius technology, the magnetic code carrier consists of two magnetic encoder tracks. The outer track consists of an even number of alternately magnetized poles and is used for high-precision position determination. It is therefore referred to as the master track. The second inner track has one fewer pair of poles than the outer track and is therefore referred to as the Nonius track. This track is used to calculate an absolute position within one revolution of the pole disk. This is done by calculating the angular difference between the two tracks. Encoders with this technology must be calibrated before use. An alternative option to Nonius technology that does not require calibration is AksIM technology.
