Product Description
Ordering Key
The ET1820 is a family of gen-
eral purpose through-beam
sensors in an industrial stan-
dard M18 nickel-plated brass
housing for heavy duty appli-
cations. They are useful for
simple applications where a
basic sensor provide adequate
sensing performance. The sen-
sors are easy to adjust with a
270° single turn potentiometer.
The output is a 4-wire comple-
mentary (NO and NC) circuit
with NPN (current sinking) or
PNP (current sourcing) open
collector transistor output.
