ンコーダ付リニアスライドテーブル。 A linear slide table that incorporates a rail into the guide section of the table and bed to perform linear motion.
On the table part, the direction of the magnetic poles is alternately reversed,
At least one wire or shaft-shaped linear scale made of a magnetic material with high coercive force and magnetized regions at equal intervals is incorporated in parallel to the stroke direction, and the bed portion has a magnetoresistive effect element. A linear slide table with an encoder, characterized in that a sensor is incorporated in a position that does not impede movement of the table so as to always maintain a constant distance from the scale.
