ET 18 20 NPA S-1
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.
