Features magnetic grid

Magnetic grid is an important feature of the magnetic scale in contact with the head of the working condition. The working principle of the magnetic grid is a magnetic-electric conversion, in order to ensure a stable head output signal amplitude, given the reluctance of air is large, the magnetic scale and the magnetic head is allowed between a large and variable clearance, preferably contact type. With this magnetic head at the time the gate is at work on the tape pressed into, Neodymium Motor Magnet so that there is not real-time with a surface smooth, the magnetic head and the tape can be a good contact. Linear magnetic grid of magnetic scale and the gap between the heads of about 0.01mm, assembly and adjustment can not be achieved because the ideal state, so in fact quasi-linear magnetic grid is also in contact working condition.Another important feature of magnetic grid is the magnetic scale in a certain tension.
