The Carlo Gavazzi Type EO1804 Proximity Sensor is a general purpose diffuse-reflective sensor 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 270° single turn potentiometer. The output is a 4-wire complementary (NO and NC) output in NPN (current sinking) or PNP (current souring).
