20 m through-beam emitter — range sets the pair spacing
The XUB0AKSNL2T is the emitter half of a through-beam photoelectric pair, rated for a 20 m sensing distance between emitter and receiver. That range covers long conveyor lanes, automated warehouse aisles, and wide machine access zones where a single sensor pair spans the full gap. Response time is 2 ms — fast enough to catch parts moving at several meters per second on a packaging line, but check that the downstream PLC input filter is set to at least 500 Hz to avoid missing pulses.
12-24 VDC, 3-wire — wiring constraints for the integrator
Runs on 12 to 24 VDC nominal, 3-wire configuration (brown/blue/black) with a 2 m PVC cable pre-attached. The third wire is the switched output — typically PNP NO for sinking PLC inputs. No separate power supply needed if the control cabinet already has a 24 VDC bus. The plastic barrel (18 mm diameter, front sensing) eliminates corrosion concerns in washdown environments compared to nickel-plated brass housings found on older XU2 series sensors. Mounts in standard 18 mm through-hole brackets or clamp mounts.
IP67, NEMA 4X/12 — enclosure rating for wet or dusty lines
IP67 and NEMA 4X/12 mean the sensor body and cable entry are sealed against hose-directed water and dust ingress. Suitable for food processing washdown, outdoor conveyor systems, and machining coolant spray — the PMMA lens resists many industrial chemicals and cleaning agents.
Sourcing and lifecycle — active, quoted to order
For volume purchases or scheduled releases, the 2 m cable length and plastic housing are the fixed configuration — no field-interchangeable connector option on this variant. The UPC is 78590150983 for traceability in procurement systems.
