This encoder series also features line drivers with active termination for long cable runs as well as 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 drives a pulse every 180º. 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/LD degradation issues, the ED-20 has a virtually unlimited life.
