Response time of 30 ms is the limiting edge rate for downstream counting or high-speed detection; for conveyor-edge or part-present duties well below roughly 10 Hz it is comfortably adequate, but high-speed indexing lines will outpace it. Operating temperature runs −25 to 55 °C, which covers unheated warehousing and most factory-floor enclosures; derating above 40 °C follows the standard curve and should be checked against cabinet interior temperature, not ambient. ## Form factor, body, and wiring The housing measures 5.8 × 4 × 6 cm with a wire-lead terminal exit, suitable for cable gland entry into a junction box rather than a quick-disconnect M12 plug; replacement harnesses must be specified against the lead-side wiring, not a connector keying. ## Lifecycle: mature line, replaced by E3JK-DR12-C The product is recorded at lifecycle stage mature, and Omron's own listing names a direct replacement: E3JK-DR12-C.","metaTitle":"Omron E3JK-DS30M1 Diffuse Photoelectric Sensor, 0.3 m, Relay","metaDescription":"Omron E3JK-DS30M1 diffuse-reflective photoelectric sensor, 0.3 m range, relay output, 24–240 VAC supply.
