Omron offers a selection of industrial photoelectric sensors for use in your production lines, including the popular E3Z series of products. However, when repairing old equipment with these sensors within it, you may discover parts marked ‘E3V3’ instead. Could an E3V3 series part such as E3V3-D81 be replaced with an E3Z-series replacement like E3Z-D81?
The E3V3 series from Omron is obsolete and no longer supported through either production or documentation. While third-party websites still have archived copies of E3V3 equipment manuals, no first-party documentation remains for this product series. We have confirmed with Omron that the E3Z series is their recommended replacement for the older products. While your maintenance teams will have to verify compatibility with older equipment, in most cases you should be able to get an E3Z series part working in your equipment with relatively minimal fuss and bother.
