The Omron E3Z-T81K is a compact through-beam photoelectric sensor rated for a 15 m sensing range, covering long-reach detection on conveyors or pallet transfer lines. The standard sensing object is an opaque 12 mm dia. minimum, so the beam break is reliable for most part-present applications. Current consumption is 35 mA max, which stays within the typical sourcing capacity of a PLC output module without an interposing relay.
