| 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 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.
