Self-Contained Photoelectric Controls

Self-Contained Photoelectric Controls combine the function of a reflective skanner and a DC powered control in one package. This has several advantages for the user. Hookup is simplified by having one device to wire up rather than two. Interference by electrical noise generated in industrial environments is minimized by reducing the distance from the sensor to the control to zero. Most units are directly compatible with a programmable controllers, and can be connected with just a three or four wire hookup. A Self-Contained Photoelectric Control has a lower purchase price than a separate skanner and control thus reducing inventory cost.
