The NPN output is selectable for light-ON or dark-ON. Pre-wired with 2 m cable; no connector to seat, so wire directly into the terminal block. Zinc die-cast case, IP67 rated, and operating temperature -25…55°C make it suited for washdown or ambient-temperature lines. ## Not a drop-in for E3SR67—here is the delta The closest NPN peer in the E3S family is the E3SR67, but it is not a mechanical or electrical substitute for the E3SGS3E4. The E3SR67 uses an M12 connector, while this part has a 2 m pre-wired cable—rewiring is required. More important, the E3SR67 senses 100…300 mm versus the 30 mm fixed range here. If your line needs short-range fork detection, the E3SGS3E4 is the correct part; the E3SR67 overshoots the gap. ## Mounting and wiring checklist Mount the fork so the object passes cleanly through the 30 mm gap; the infrared LED (950 nm) emitter and receiver are aligned internally. Sensing requires an opaque target at least 6 mm diameter. Wire the three leads (brown: +V, blue: 0V, black: NPN output) to a 12…24 VDC supply. Select light-ON or dark-ON by the position of the built-in switch—no configuration overhead. The zinc die-cast housing provides good mechanical rigidity; IP67 seals protect against coolant splash and dust. ## Lifecycle and supply posture Lifecycle status is current, meaning Omron continues to manufacture the E3SGS3E4. No last-time buy notice or phase-out is flagged. Sourcing is via standard RFQ through our stocking channel.","metaTitle":"Omron E3SGS3E4 Fork Photoelectric Sensor, 30mm, NPN, 12-24VD","metaDescription":"Active production Omron E3SGS3E4 fork photoelectric sensor, 30 mm sensing range, NPN output, 12...24 VDC, IP67, 1 ms response.
