A miniature all-purpose push-button photoelectric sensor has been introduced. The new EZ-EYETM has been designed to perform a multitude of sensing applications including object detection, Web break detection, counting, inspection, orientation, and more. Features include setup with the single push of a button, flash rate indicator for easy alignment, higher gain adjustment by tapping button, sensing mode optical block selection, infrared (IR) or red LED light sources, both NPN and PNP output transistors, pulsed modulated light source that is immune to most ambient light including strobes, and 10 to 24V dc power supply requirement.
