　　Description: The ED-20 series magnetic encoder is designed for medium duty industrial feedback applications with ball bearing supported shaft. Resolutions are available from 200 to 400 counts per revolution. This encoder series also features line drivers with active termination for long cable runs and reverse voltage protection. The ED-20 also offers the option of high voltage differential, low voltage differential or open collector (NPN) outputs. An index channel which offers a pulse every 180º is also included. The magnetic technology used in the ED-20 series offers many advantages over conventional optical encoder technology such as sealed electronics and extended temperature ranges. Furthermore, since there are no LED degradation issues, the ED-20 offers a virtually unlimited life.
