The Omron E3B2-D2M4-G is a photoelectric sensor with a relay SPDT output rated for 3 A at 250 VAC (p.f.=1) and a minimum switching load of 10 mA at 5 VDC. The supply voltage covers 24–240 VAC and 12–240 VDC, meaning it can run directly off a PLC power supply or a control transformer without an external DC converter. The 0.5–20 s time range, combined with the selectable Light-ON/Dark-ON mode, handles both presence and absence detection on the same wiring pair—useful when you're replacing a sensor in a panel that didn't leave room for a separate timer.
The 1/2-14 NPT conduit entry accepts standard liquid-tight fittings, so it lands directly into a washdown-rated enclosure without an adaptor. IP66 protection handles direct hose spray, making it viable on food, beverage, or packaging lines. The polycarbonate housing is impact-resistant; dimensions 90 x 36 x 80 mm fit a slim 36 mm wide body on a bracket or machine frame.
