Omron photo eye wiring diagram. Compact photoelectric sensor with built in amplifier the standard for photoelectric sensors with a secure track record of one million sold yearly. The short answer is yes but i think it justifies more of an explanation. Photoelectric sensors technical guide 9. With the photo eye removed from the circuit and if you have a ohm meter you can test the ohms thru the black and red wire coming out of the photoeye. When you shine light in the face of the photo eye you should see a increase in resistance and when you cover up the photo eye the resistance should drop to close to zero allowing current to pass. From long sensing range to oil resistance omrons photoelectric sensing portfolio covers all the features required for advanced applications.
