EP1820NPAS

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 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 applications, where a basic sensor Ordering Key provides adequate sensing performance. The sensors are easy to adjust with a 270° single turn potentiometer. The output is a 4-wire complementary NO or NC thyristor (SCR) output.
