The Omron E3SR67 is an NPN retroreflective photoelectric sensor from the E3S series, offering a sensing range of 100–300 mm with a 1 ms response time. It operates on 10–30 VDC and switches up to 100 mA loads, making it a direct fit for packaging, material handling, and conveyor lines that use sinking (NPN) PLC inputs. The infrared LED emitter and M12 connector simplify panel wiring with IP67 protection for wet washdown zones.
The E3SR67 is mechanically identical to the E3SR87: same 29.2 mm width, 50 mm length, sensing range, response time, and M12 connector. The sole difference is the output polarity — the E3SR67 is NPN, while the E3SR87 is PNP. If your installed base uses a PNP input card, the E3SR87 drops in without rewiring; the E3SR67 requires swapping the output type or adding a signal converter. For a panel already wired for NPN, this sensor is a direct spare.
