Magnetic encoder and a method for producing the same |
摘要 |
In construction of a peripheral-magnetization type magnetic encoder having a rotary spindle and a magnetic head, a resin housing is formed by insert moulding so as to embrace the spindle leaving a slight tubular clearance to allow free axial rotation of the spindle, thereby providing direct, simple and stable support to the rotary spindle for enhanced precision in direction.
