The Omron E3B2-R5M4D-US-3 is a through-beam photoelectric sensor with a 5-meter sensing range and an adjustable timer from 0 to 5 seconds. Its supply voltage covers 12-240 VDC or 24-240 VAC, so it works on just about any control voltage you've already got in the panel.
That 5m range is good for long conveyor belts or across wider gaps where you'd rather mount one sensor than two. The built-in timer (0-5 sec) gives you a delayed output—handy for synchronizing with a downstream action or filtering out short interruptions. The wide voltage input means you don't need a dedicated sensor power supply; it'll pull from 12-240 VDC or 24-240 VAC as-is.
Where you'll see it
Typical spots: material handling lines, packaging machines, automated storage systems—anywhere a break in the light beam signals a product or pallet. The timer can stretch the output signal so a PLC has time to read it, or hold it long enough to ignore a brief gap.
Sourcing this code
You've come with this exact order code—E3B2-R5M4D-US-3. It's not an oddball variant; it's a standard Omron part that runs through normal distribution. For a line-down or BOM freeze, quote it against your RFQ and we'll confirm lead time against your volume.
