Photoelectrics Retro-reflective, Polarized Type EP 1820, DC, PBTP-housing • Range: 2.0 m • Modulated red light, polarized • Supply voltage: 10 to 40 VDC • Output: 200 mA NPN or PNP • Make and break switching functions, LED, indication • Protection: Reverse polarity, short-circuit, transients • Improved immunity to reflecting surfaces • Heavy duty M18 metal housing, IP67 • Cable and plug versions 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. Type Housing diameter Range Output type Housing material Connection type Type Selection HousingRatedConnection Ordering no.
