Type EO1804.PAS, DC, Metal-housing
The EO1804 is a family of
general purpose Diffuse-
reflective sensors in a short
M18 metal housing for
heavy duty applications.
They are useful for simple
applications where a basic
sensor provides adequate
sensing performance. The
sensors are easy to adjust
with 270 single turn poten-
tiometer. The output is a 4-
wire complementary (NO
and NC) output in NPN (cur-
rent sinking) or PNP (current
souring).
