Ordering Key
The EP1830 is a family of
general purpose polarized
retro-reflective sensors in a
short M18 metal housing for
heavy duty applications. They
are useful for simple applica-
tions, where a basic sensor
provides adequate sensing
performance. The sensors are
easy to adjust with a 270° sin-
gle turn potentiometer. The
output is a 4-wire comple-
mentary NO or NC thyristor
(SCR) output.
