It detects objects up to 300 mm away from a standard white paper target (100×100 mm). The relay output switches loads from 0 to 3 A, making it a direct replacement for older panel-wired sensors without needing a separate amplifier or solid-state interface. It runs on either 12 to 24 VDC or 24 to 240 VAC, so it drops into existing control circuits without a supply swap — handy for a line-down swap where the panel voltage isn't standardized. The operation mode is fixed to Dark-ON, meaning the output relay energizes when the received light drops below the threshold (object present). No Light-ON/Dark-ON selector here — if your application needs Light-ON, this isn't the part. This part is in mature lifecycle stage. Confirm availability and pricing at quote time. The 300 mm sensing distance is measured against a white paper target. Real-world range drops with darker or less reflective surfaces — the differential distance is 20% max of the sensing distance, so expect some hysteresis. For a dark target (black rubber, matte plastic), the effective range may be half the rated value or less. The relay output handles 0 to 3 A resistive load. That's enough to drive a small contactor coil, a PLC input, or an indicator lamp directly. No transistor switching here — the relay gives you isolation but also a finite mechanical life; factor that into high-cycle applications. Emitter draws 15 mA DC max, receiver 20 mA DC max.","metaTitle":"Omron E3JK-DS30M2 Diffuse Photoelectric Sensor, 300mm, Relay","metaDescription":"Omron E3JK-DS30M2 diffuse-reflective photoelectric sensor. 300mm range, relay output, 12-24 VDC / 24-240 VAC.
