Description
The HEDT-9000 and the HEDT-
9100 series are high
performance, low cost, optical
incremental encoder modules that
operate to 125°C. When used with
a codewheel, these modules
detect rotary position. The
modules consist of a lensed (LED)
source and a detector IC enclosed
in a small C-shaped plastic pack-
age. Due to a highly collimated
light source and unique
photodetector array, these
modules are extremely tolerant to
mounting misalignment.
The two channel digital outputs
and the single 5 V supply input
are accessed through five 0.025
inch square pins located on 0.1
inch centers.
