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 1024 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.
