Product Description
Ordering Key
EP 18 20 NPAS-1
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 basicsensor
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 orNC thyristor (SCR) output.
